E SERIES Progressing Cavity Pumps
The E SERIES progressing cavity pumps are ideal for transferring a wide range of fluids requiring dosing accuracy.
By minimising aeration and agitation of fluids, they ensure gentle product conveyance without altering their organoleptic characteristics.
Wear parts can be easily replaced on site.
The E SERIES progressing cavity pumps are suitable for the gentle and pulsation-free conveying and dosing (flow rate proportional to rotational speed) of various aggressive and non-pulsating substances, with or without solid components, with low to medium viscosity (up to 20,000 cP), sticky, shear-sensitive, lubricating and non-lubricating substances.
These pumps can use different types of process connections according to international standards (EN, DIN, ANSI, GAS and others), or have a special design.
They can also be supplied in different types of materials (e.g. CAST IRON, STAINLESS STEEL and others) depending on application contexts.
The E SERIES progressing cavity pumps achieve flow rates up to 3.000 l/h and pressures up to 14 bar.
Minimal on-site maintenance
Space-Saving Monobloc Construction
Continuous flow and minimal turbulence
Suction without foot valve
Customised executions according to request
The rotor is available in many materials depending on the type of application: carbon steel with thick chrome plating, AISI 304 (1.4301) stainless steel, AISI 316 (1.4401) stainless steel and others on request. In addition, ‘standard pitch’ or ‘ long pitch’ geometry is possible.
The stator is made of vulcanised rubber inside a steel tube, with integral seals on both in a variety elastomer (NBR, HNBR, EDPM, FPM and more on request). It is possible to have the inlet with hopper-shaped opening for improved feed of the product into the pumping part.
Different types of joints and transmissions are available to suit a variety of applications:
Different types of process connections are available according to international standards (EN, DIN, ANSI, GAS and others) or in special designs. Different types of materials (e.g. CAST IRON, STAINLESS STEEL and others) are possible depending on application contexts.
The E SERIES progressing cavity pumps are supplied with a mechanical seal as standard:
The drive motor is directly flanged to the pump support lantern, resulting in compact dimensions, low total weight, easy maintenance and economic advantages.
