MB Pumps Brochure

The Product

The commitment of ETS MENGIN to developing innovative

solutions to pumping problems, resulted in the launch of the

PS range of MENGIN cutter pumps.

The design of the pump is based on a channelled impeller

with blades extended into a sharp edged spiral cone rotating

against a fixed adjustable knife with a hardened steel blade.

Fibrous waste and debris in suspension are chopped into

pumpable segments, allowing blockage free flow through the

pump.

The MENGIN PS series is a range of pumps available in six

different formats for use in wet or dry well installations.

Difficult pumping applications which are solved by utilising

a MENGIN cutter pump include unscreened raw sewage,

primary and secondary tank de-sludging and storm overflow

in the water and waste treatment industries... wood pulp in

the paper industry... animal hide and fleshings in the tannery

industry... vegetable waste in the food industry; as well as

many other sludges and slurries containing plastic bottles,

rags, bits of wood, etc... all successfully pumped with no risk

of blockage.

Incorporating 2, 4 or 6 pole electric motors rated from 3

to 125kW, the PS range of MENGIN cutter pump offers a

range of capacities from 2 to 500 litres/sec. against heads

up to a maximum of 70 metres. Flame proof motors are

available and pump bodies can be cast iron or stainless

steel whilst the cutting impeller can be strengthened by the

addition of tungsten carbide.

ApplicationsThe design of the Mengin cutter pump ensures that fibrous waste and debris in suspension are chopped into pumpable segments allowing blockage free flow through the pump.

The unique solids cutting mechanism makes the Mengin cutter pump suitable for many difficult, heavy duty pumping applications and guarantees substantial reduction in maintenance time and costs.

Cutter MechanismMengin cutter pumps have a channelled impeller with blades extended into a sharp edged cutting cone which rotates against a fixed, adjustable knife with a hardened steel blade.
