PROGRESSING CAVITY PUMPS E-SERIES MONOBLOCK DOSING E-SERIES

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:

• High-strength pin joint protected by sleeve in various rubbers in carbon steel version for industrial use and stainless steel for chemical environment use;
• Cross joint protected by sleeve in various rubbers in carbon steel version for industrial use and stainless steel for chemical environment use;

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:

• Single component mechanical seal: bidirectional single spring, unbalanced, with elastomeric bellows encased in a steel jacket, distinguished by its short length.

The drive motor is directly flanged to the pump support lantern, resulting in compact dimensions, low total weight, easy maintenance and economic advantages.
