Canned Pump

A: If you need to revise the product design or specification of cryogenic equipment, please let us know as soon as possible. We will work with you to understand the changes you require and provide a new design or specification that meets the need. Please keep in mind that depending on the extent of the revisions may impact the delivery timeline or pricing of the product.

A: "At Zoiun, we offer highly competitive pricing on a wide variety of solutions for cryogenic applications. We also provide further discounts for large quantity orders. In the event that you cannot find the cryogenic equipment you need on our website, we are more than happy to source promotional pricing through our sister companies to ensure that your needs are met."

A: If you need to cancel an order, please inform us as soon as possible. It's important to note that our production process begins immediately after we receive the deposit in our bank account. We have a buffer period of 1 or 2 days for returning the payment, which normally takes 1 or 2 days to get into our bank account. However, once the production has started, cancellation may not be possible and may result in cancellation fees or forfeiture of the deposit.
We understand that unexpected circumstances may arise, and we will work with you to find the best solution. If you need to cancel your order, please contact us as soon as possible and provide the reason for cancellation. We will do our best to accommodate your needs while minimizing any impact on production timelines or costs.

A: The stator is canned in the air gap, confining the liquid in the rotor chamber. The pump liquid circulates through the rotor chamber, cooling the motor, and lubricating the slide bearings that support the rotor. The casing of the chamber forms a sealless enclosure that confines the liquid without any dynamic sealing.

A: Unlike traditional pumps that rely on seals and gaskets, canned motor pumps eliminate the risk of leakage. This makes them ideal for handling toxic, flammable, or corrosive fluids, ensuring both safety and environmental compliance.

A: A canned pump, also known as a hermetically sealed pump, is a type of centrifugal pump in which the motor and pump are enclosed within a single, sealed housing. This design eliminates the need for mechanical seals, preventing leakage of hazardous or toxic fluids.

A: Magnetic drive motors have a single containment zone. This means the fluid is contained in a single-walled can. A canned pump, on the contrary, has double containment where the fluid is encased in a sealed can (stator liner), which in turn is encased in the pressure-proof motor casing.

A: The key components include the impeller, stator, rotor, containment can, thrust bearing, radial bearing, suction casing, and discharge casing.

A: The pumped liquid circulates through the motor section, absorbing heat from the stator and rotor, and then returns to the main flow. This provides both cooling and lubrication.

A: Because they eliminate the possibility of fluid leakage, they prevent emissions of hazardous or volatile substances into the atmosphere, contributing to a cleaner and safer environment.
