LTLS Series Agri-food Progressing Cavity Hopper Pumps

AGRI-FOOD PROGRESSING CAVITY HOPPER PUMPS AND INFEED SCREW MONOBLOCK - LTLS SERIES

with direct coupling and additional infeed paddles FOR WINE INDUSTRY

THE IDEAL PUMPS FOR TRANSFERRING WHOLE GRAPES AND FERMENTED GRAPES

The LTLS SERIES agri-food progressing cavity hopper pumps are particularly suitable for pumping whole and crushed grapes (with and without stalks) and fermented grapes.

By minimising aeration and agitation of fluids, they ensure the gentle product conveyance without altering their organoleptic characteristics.

Wear parts can be easily replaced on site.

The LTLS SERIES agri-food progressing cavity hopper pumps have a hopper design that allows easy entry of the product into the pump; in addition, the presence of the side additional infeed paddles ensures a constant supply of product to the pump, preventing the medium from stagnating above the infeed screw.

Process connections can use different international standards (EN, DIN, TRI-CLAMP, SMS, GAROLLA, GAS and others) or can have a special design.

They can also be supplied in different types of stainless steel (e.g. AISI 304, AISI 316 and others) depending on application contexts.

The LTLS SERIES agri-food progressing cavity hopper pumps achieve flow rates up to 110 m3/h and pressures up to 14 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. In addition, ‘standard pitch’ or ‘long pitch’ geometry is possible. Inoltre, è possibile la geometria a “passo standard” o a “passo allungato”.

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.

The auger coupling shaft, for the transmission of motion from the drive to the rotor, can be realised with different types of joints to suit various applications.

  • Cross joint protected by sleeve in various rubbers in stainless steel version;
  • Cross-cover joint protected by sleeve in various stainless steel rubbers;

The pump body is made with a rectangular/square hopper, with the possibility of adapting its dimensions to suit the specific application.

Different types of process connections are available in delivery according to international standards (EN, DIN, TRI-CLAMP, SMS, GAROLLA, GAS and others) or in special designs. Different types of materials (e.g. STAINLESS STEEL and others) are possible depending on the application contexts. Sono possibili diverse tipologie di materiali (ad es. ACCIAIO INOX ed altri) in funzione dei contesti applicativi.

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.
  • Single mechanical seal for food grade products: mechanical seal constructed in accordance with UNI EN 12756 (ex DIN 24960). Balanced. Mechanical seal with built-in shaft sleeve, single leaf spring and/or multi-spring protected. Bi-directional direction of rotation. Easily cleaned free stagnation points. Suitable for FCMs (Food Contact Materials) processes. 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.
