The Debem MB Series of resin encased centrifugal pumps are chemically resistant pumps specifically designed for acids and alkalis or very dirty liquids. The MB series pump has an open impeller design enabling it to handle liquids with a viscosity up to 500cps, and small suspended solids.
Two versions of the MB plastic chemical centrifugal pump are available; with either a lip seal or bellows (mechanical) seal of which selection is based on the liquid being pumped. This chemical pump casing is of single piece construction and weldless meaning any acid transferred will not attack the welds, which is a common weak area in welded pumps. This horizontal centrifugal pump requires a flooded suction in order to operate.
Features of the Debem MB Single Stage Centrifugal Pump:
- Horizontal centrifugal pump
- Available with lip seal or mechanical seal
- Lift capability of 0M - Flooded
- IEC & NEMA motors available in single and 3 phase 50hz/60hz
- Zero welds and single piece construction ensures longevity
- Extremely easy maintenance
- Available in PP or PVDF

FAQs
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.
Under extremely high temperatures or excessive torque the magnets may decouple meaning that the pump shaft can slip causing stoppages and inefficiencies.
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.
No! The presence of solids can stick to the magnets and interfere with the operation of the pump.
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.
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.
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.
