U SERIES Agri-food Progressing Cavity Flanged Pumps

AGRI-FOOD MONOBLOCK FLANGED AGRI-FOOD PUMPS - U Series

with direct coupling

COMPACT VERSION IDEAL IN THE OIL INDUSTRY

The U SERIES agri-food progressing cavity flanged pumps are ideal for the different stages of the olive oil production process.

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 U SERIES agri-food progressing cavity flanged pumps are self-priming, which means they have the ability to create a vacuum, allowing suction even under unloaded pipe conditions.

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.

U SERIES agri-food progressing cavity flanged pumps achieve flow rates up to 15 m3/h and pressures up to 12 bar.

TECHNICAL DETAILS

The rotor is available in many materials depending on the application: stainless steel AISI 304 (1.4301), stainless steel AISI 316 (1.4401) and others on request.

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.

Cross joint protected by sleeve in various rubbers, in stainless steel.

Different types of process connections are available according to international standards (EN, DIN, ANSI, GAS and others) or in special execution; FDA food grade aluminium alloy material.

There are various types of seals:

  • Gland Packing: standard seal with packed rings at low friction coefficient. Solution with low installation costs. Used in processes with medium solids content at medium abrasion. Pressure (on shaft seal): up to 2 bar.
  • Single component mechanical seal: mechanical seal constructed in accordance with EN 12756 (ex DIN 24960). Unbalanced. Two solutions are possible: single cylindrical spring with elastomer bellows or leaf spring and/or multi-spring and o-ring seal. Bi-directional direction of rotation. Suitable for processes with viscous products and low dry percentages. 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.
