How does a mag drive pump work?

The drive magnet is attached to the shaft operated by the motor. As the motor turns on, it spins the drive magnet which in turn spins the magnet attached to the impeller. The rotation of the impeller produces the power that drives the liquid through the pump.

Where are magnetically coupled pumps used?

Due to their seal-less design meaning they are not prone to leaks, magnetic drive pumps are very popular for the pumping of flammable, toxic and hazardous chemicals, acids and other potentially dangerous fluids that do not contain abrasives.

Can a magnetic drive pump handle solids?

No! The presence of solids can stick to the magnets and interfere with the operation of the pump.

Can a mag drive pump lose its magnetism?

Under extremely high temperatures or excessive torque the magnets may decouple meaning that the pump shaft can slip causing stoppages and inefficiencies.

What information do you need to quote me for Debem pump parts?

To ensure you get the correct Debem spare parts, we need to identify the exact Debem pump model you have. Please advise us of the model number and serial number which can be found on the pump label which is usually on the top of the pump body.

I need a Debem pump parts distributor near me, can you help?

Castle Pumps can supply all Debem pump parts detailed on the spare parts list including diaphragms, balls, ball seats and casings.

Can I get a chemical pump for use with multiple chemicals?

We would need to cross check compatibility of the materials of all chemicals you wish to pump, but it is possible. If you are pumping multiple different liquids or where cross contamination is not desirable we suggest using the F310 or F430 chemical drum pumps.

Does concentration of my chemical matter for pump selection?

Yes this is absolutely something to consider for chemical transfer pumps! A material’s resistance to a chemical can change depending on the concentration of the chemical and the temperature. For example, Hastelloy C is compatible with Sulphuric Acid at 98% concentration and up to 60°C, but at 80% Hastelloy C is only compatible up to 20°C.

Debem DM Centrifugal Magnetic Drive Pump - Datasheet

Enquire now about this product

The Debem DM Series of magnetic drive pumps is a centrifugal pump that is magnetically coupled available in polypropylene (PP) or in Polyvinylidene fluoride (PVDF). This range of mag drive pumps are low maintenance and designed for applications that seal less pump is required. Suitable for transferring clean liquids that do not contain any solids in suspension, including highly corrosive, toxic, noxious and carcinogenic liquids, Debem DM magnetic drive pumps are ideal for continuous running applications. This centrifugal magnetic drive pump requires a positive suction pressure to function correctly and can handle liquids with a viscosity up to 150cps.

Thanks to its polypropylene or PVDF constructed body combined with its seal-less, anti-leak design, the DM magnetically coupled centrifugal pump is popular for applications that include aggressive chemicals and acids and is typically used as a chemical transfer pump. The magnetic coupling also increases the safety of the pump by significantly reducing the chance of corrosive liquids leaking thanks to the absence of a mechanical seal that is prone to wear.

FAQs

Rather than having a mechanical seal to prevent liquid escaping from between the motor and pump shaft, magnetically coupled pumps use two magnets. The absence of mechanical seals that are prone to wear reduce the chance of leaking and maintenance.
