What is Chemical-Resistant PVDF Magnetic Pump?
Before examining the features and advantages of this 12-volt chemical pump/ magnetic pump, let’s first explore what it is. This pump has been tailored to reliably transport corrosive liquids while staying dependable. It has several exceptional features, including:
PVDF (Durable & Reliable Construction)
PVDF (polyvinylidene fluoride) is a highly resistant thermoplastic fluoropolymer known for its rigidity, chemical resistance, & strength. It can withstand extreme temperatures with great mechanical strength and can be used in practically any environment.
Moreover, PVDF is highly resistant to UV radiation, hydrolysis, hydrogen peroxide attack, and corrosion caused by acids. Its incredible electrical insulation properties also make it an optimal choice for a bevy of applications.
As such, PVDF pumps are capable of withstanding even the toughest challenges, making them an outstanding choice for any industrial or chemical-related applications. They also provide constant performance without demanding too much maintenance due to their uncomplicated design. Thus, allowing you to experience consistent excellence while keeping time spent on upkeep minimal.
The 100% leak-proof feature of these pumps prevents any kind of fluid from getting inside the pump’s body. They can efficiently process highly corrosive chemicals, plating chemicals, and fuming liquids due to their versatility.
Additionally, the economical price tag (combined with low maintenance costs) makes these pumps a great investment choice that can save costs in the long run. Even better, the favorable pricing does not sacrifice performance or reliability!
Magnetically driven pumps, also known as mag drive pumps, are an innovative type of chemical process pump that use a synchronous magnetic drive system to move fluids without the need for a mechanical shaft seal. This significantly reduces the cost of the pump and its daily operating costs, as it eliminates the requirement for any mechanical seals, sealant tanks, or cooling lines.
They utilize two sets of magnets – one externally mounted to the motor, and the other located internally in the liquid being pumped. The rotor is connected to these magnets, and their attraction causes it to rotate when the motor’s shaft rotates.
Due to this movement, fluid is pulled in at one side and forced out from the other side. As pressure boundaries – including containment or shrouds – separate these two sets of magnets, no liquid can escape from around the shaft. This ensures that no contamination can occur and pumping can be done reliably over short periods or for long durations without issue.
It is critical to select an appropriate magnetic drive pump supplier, depending on what needs to be pumped and operating conditions. Horizontal single-stage models are suitable for low flows while vertical side-channel impellers are ideal for larger flows and high heads.
Installation requirements of mag drive pumps vary depending on the model but generally speaking, they require less space than traditional centrifugal process pumps, making them an excellent choice where space is limited.
How Do Chemical-Resistant PVDF Magnetic Pumps Work?
Magnetic drive pumps use a combination of rare earth metals and permanent magnets to power an impeller. The rare earth alloy magnets are divided into two concentric rings, one attached to the motor’s drive shaft, and the other attached to the driven shaft of the impeller.
When the alternating poles of these magnets come close together, a magnetic torque is created, which turns both rings in unison at the same speed. This arrangement provides several advantages over traditional pumping systems.
Firstly, because rare earth alloys require less mass than iron magnets to maintain a specific torque, they can create smaller and more efficient pumps than their counterparts. This helps reduce overall machine size, complexity, and cost. Secondly, because these alloys have greater temperature stability than traditional magnets, they need less maintenance or repair over time due to thermal damage or wear out.
However, there are some disadvantages associated with using these materials. For example, the cost can be a major factor. Due to their complex production process, most rare earth metals are mined in only a few places globally, leading to price volatility.
Additionally, most of these alloys corrode easily when exposed to air/water. Therefore, manufacturers need to take measures for protection against corrosion when designing those parts that are subjected directly to the pumped fluid media (such as inner ring magnets).
To overcome this issue, protective resins must be applied or corrosion-resistant casings such as polypropylene (PP), polyvinylidene fluoride (PVDF), and ethylene tetrafluoroethylene (such as high-quality of chemical diaphragm pump). You can also get stainless steel chemical pump manufacturer to custom-make a steel-based pump.
PVDF is particularly useful for applications involving chemicals and abrasives, which traditional motors can’t handle due to their vulnerability. Magnetic drive chemical pumps are constructed with a highly durable PVDF material that is resistant to corrosion, abrasion, and chemical attack.
Benefits of Using Chemical Resistant PVDF Magnetic Pumps?
Magnetic drive pumps offer a wealth of benefits that make them an ideal choice for a range of applications. From improved productivity and increased safety to greater resistance to corrosion, leak prevention, and the ability to run dry, mag drive pumps provide cost-effective solutions with reliable performance.
For starters, the innovative design eliminates any openings in the back of the pump allowing for a hermetic seal and thus eliminating the need for replacement seals which can incur labor costs and downtime. This ultimately reduces cost in parts and labor over the lifetime of the pump – and has a dramatic effect on the bottom line.
Magnetic drive pumps are also an effective way to ensure safe operation within industrial environments as they help reduce potential risks such as hazardous leaks from toxic chemicals or other volatile compounds such as VOCs or VHAPs. This helps contribute to compliance with safety standards.
Furthermore, these pumps possess strong durability against running dry operations, making them suitable for production applications where constant supervision lacks. Their robust nature allows them to withstand even corrosive substances, making them well-suited for tough jobs that require tough solutions while simultaneously simplifying the pump selection process due to its versatility.
With this knowledge in mind, it is clear why these pumps should be heavily considered when selecting a suitable solution for your needs. Get a magnetic drive pump manufacturer and acquire one!
Disadvantages of Chemical Resistant PVDF Magnetic Pumps
Liquids Containing Ferrous Particles.
Liquids containing ferrous particles, such as iron oxide, can be problematic. This is because the particles can collect on the impeller magnet over time, resulting in the pump ceasing to function.
Loss of Energy through Coupling.
Some energy is lost in the coupling, primarily due to some magnetic resistance. This can reduce the overall efficiency of the system.
More Initial Capital.
These pumps are more expensive than mechanical seal pumps. However, the maintenance cost is significantly reduced.
The difference in appearance as the two kinds of pumps as below:
Standard Centrifugal Pump vs. Magnetic Drive Pumps
Standard centrifugal & magnetic drive pumps are two distinct technologies used to move liquids and gases. Although they have similarities, they are designed with different goals in mind, leading to considerable differences in their operations.
- Standard Centrifugal Pumps
SCP generally consists of a rotating impeller driven by an electric motor, which creates kinetic energy in the pumped medium, resulting in increased liquid pressure at the outlet. The main components of this type of pump are the casing, impeller, and shaft seal.
To prevent leakage around the pump shaft (due to pressure created by the entry of media into an enclosed space), some form of a seal is needed. Three common types of seals used with standard centrifugal pumps are:
- Soft packing material (usually compressed around the pump shaft in a stuffing box)
- Lip sealing or o-ring
- Mechanical sealing
With soft packing material, the packing material is held in place within the opening in the casing (the stuffing box) and compressed by a gland nut which can be progressively tightened as the packing material wears/ settles.
O-rings provide a snug, gap-less fit between two adjoining parts while mechanical seals consist of two machined flat faces pressed together more tightly than either O-Ring or Soft packing materials could manage.
However, these seals cannot entirely prevent leakage, resulting in increased energy costs and environmental contamination. This is where magnetic drive pumps 12v/ 12v chemical pump come in handy! You can also choose other power configuration such as 115v and 230v.
- Magnetic Drive Pumps (MDP)
MDP work on different principles from SCP. They use magnets instead of an impeller for moving fluids or gases through a sealed pipe. As there is no need for mechanical seal, this technology has been gaining ground over traditional methods as it eliminates leakage issues – ideal for hazardous substances where containment integrity is paramount.
How to Choose the Best Magnetic Drive Pump?
Selecting the perfect corrosive chemical transfer pump is essential to guarantee efficiency and dependability. To maximize your pump’s performance, it is critical to comprehend its various categories, specifications, and application details. You can also contact a magnetic drive pump manufacturer for tailor-made corrosion resistant pumps:
There are two main types of magnetic drive pumps – rotating shaft and stationary shaft. Rotating shaft pumps are ideal for heavier-duty applications as they are often made from metal, and have higher temperature & pressure ratings. However, they require more parts, leading to more complexity and thus more maintenance costs.
Stationary shaft magnetic drive pumps are more suited for light-medium duty applications, as they typically use non-metallic components such as ceramics or plastics. They generally provide good corrosion resistance but have a limited temperature (usually 200-250°F). As fewer parts are required in these configurations, this type of pump has lower maintenance costs.
When selecting a magnetic pump, you should consider a range of specifications, especially when making decisions about the size of the pump needed for any particular application. They include:
- Flowrate (measured in liters per minute or gallons per minute)
- Pump head (pressure exerted by the fluid on an obstruction within its path)
- Power rating (horsepower) (12-volt chemical pump, 115v & 230v among others)
- Outlet diameter
- Operating temperature
All these factors affect the pump performance, and you must select a model that meets your operational and power requirements.
When investigating the use of sealless magnetic drive pumps you should take into consideration factors specific to this type of equipment, including:
- Bearing location and lubrication requirements
- Operating temperatures/preventing overheating
- Decoupling risks
Bearings in conventional pumps are typically located away from pumped media whereas those on impeller shafts in magnetic drives are lubricated using the medium itself. This can lead to problems if low flow rates occur or when the media has poor lubrication qualities.
It’s also worth noting that magnets can demagnetize if exposed to temperatures over their upper limit. As such, users should avoid dry running or other conditions which could cause extra heat gain.
Additionally, selecting a magnet material that can handle 25-50°F above expected max operating temps can help minimize risks here too. Besides, monitoring power demands can help prevent decoupling due to sudden power changes or spikes exceeding maximum torque limits on couplings used with these pumps.
Magnetic drive pumps are an ideal choice for applications where containing any potential spills is of utmost importance. That said, it’s essential to consider key specifications and application factors when selecting a pump that best matches your needs.
Besides, you can contact a chemical dosing pump supplier/ manufacturer to get any help you may need. This way, you can be 100% certain that you’ll get the best match.
