Progressing cavity pumps vertical monoblock - V SERIES

The rotor is available in many materials depending on the 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 sides in a variety elastomer (NBR, HNBR, EDPM, FPM and more on request). It is possible to have the stator 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:

• Cross joint protected by sleeve in various rubbers, in carbon steel version for industrial use and stainless steel for chemical environment use;
• Cross-cover joint protected by sleeve in various stainless steel rubbers for the wine/beverage sector;
• Homokinetic joint and/or cross cardan joint for the industrial sector;
• Homocardanic joint used in particular in high flow pumps.

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.

There are various types of seals:

• Single mechanical seal with additional quench: suitable for solid medium, adhesive, crystallizing. Pressure (on shaft seal): up to 12 bar.
• Single mechanical seal: mechanical seal constructed in accordance with EN 12756 (ex DIN 24960). Balanced. Bi-directional direction of rotation. Bi-directional direction of rotation. Suitable for processes with very abrasive products and high dryness with solid particles in suspension. Pressure (on shaft seal): up to 12 bar.

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