BTCS - Hopper pump in hygienic design

Food and hygienic pump with hopper

The design of the BTCS food and hygienic pump from SEEPEX is characterized by a rectangular hopper with a compression zone and feed screw conveyor. This makes it particularly suited for pumping highly viscous, minimally flowable products – both with and without solids. In the hygienic design, the pump is fitted with open joints. However, it is optionally available with closed pin joints.

Features and Benefits

Variable

Available with a choice of open hygienic joints or closed pin joints, suitable to your individual application

Fulfills strict hygienic standards

Certified under the 3-A Sanitary Standards (variant with open joints) and designed in compliance with the EHEDG guidelines, and fitted with FDA-approved and EU 1935-2004 compliant components

Residue-free cleaning

Special housing geometry and open, hygienic pin joints facilitate optimal cleaning and sterilization: CIP, SIP, COP

Wear resistant

Hermetically sealed elastomer sleeves are particularly suited for abrasive pumping media

Optimal conveyance

Optimal filling of conveying chambers through feed screw and conically closing compression zone

Low pulsation

Minimal pulsation and low shear characteristics allow the gentle conveyance of sensitive media

Technologies, accessories and options

Overpressure Protection

The pressure gauge switches off the pump as soon as a pre-set pressure is exceeded or not reached and protects the pump from increased wear and tear or piping damage.

Standard base plate

Short base plate B with geared motor for all standard applications.

Single-acting mechanical seal

Universal standard mechanical seal for dosing, food applications and semi-submersible pumps for sealing the plug-in shaft in the suction casing or the hopper.

Pressure Branch

With gauge connection. Flange connections alternatively to DIN or ANSI.

Rotor

Wear resistant and corrosion-resistant materials. Optionally with hard surface treatment.

Conventional geometry

With short pitches and a compact design, the conventional geometry produces high pressures.

6L geometry

With a small rotor diameter and a long pitch, the 6L geometry attains lower surface velocities and extends the service life due to its large sealing line.

Stator

In food-grade materials according to FDA, BfR and EU 1935-2004 and follows pharma regulations according to several USP classes. Light and black materials in equal wall or standard design available. Optimal, hygienic sealing of the stator through integrally molded sealing surface.

6L geometry

With a small rotor diameter and a long pitch, the 6L geometry attains lower surface velocities and extends the service life due to its large sealing line.

Equal Wall Stator

The stator with uniform wall thickness is used in situations with very high pressures or temperatures.

Coupling rod

Made of stainless steel for power transmission. Available with propellers or feed screw.

Suction casing

Made of stainless steel and internally polished with an external satin finish. The optimized pump casing with suction connection above the mechanical seal enables both product flow and CIP solutions to flow through the entire casing. The tangential CIP-connection allows effective draining. Optional: double jackets for heating.

Plug-In shaft

Designed for easy CIP, made of stainless steel and designed to mount the mechanical seal in food grade material.

Plug-In shaft connection

For easy dismantling of the pump and drive enabling quick replacement of the rotating parts and shaft seals. The plug-in shaft pin secures the shaft connection to the drive and the splash ring both secures the plug-in shaft pin and protects the bearings from contamination / gland leakage. Easy access to the pump and drive enables quick replacement of the rotating parts and shaft seals.

Lantern

A corrosion resistant design, optionally made of stainless steel, connects the pump and drive and secures the assembly to the base plate or skid.

Base plate

Tailor-made selection of base plates. The base plates can be easily combined with different drives from all major manufacturers.

Open pin joint

Hygienic joint, designed for higher pressures and flow rates providing optimal cleanliness.

Open hopper

Rectangular feed hopper with conveying screw for pumping higly visous products.

Drive

Geared motors, variable speed drives or frequency controlled motors of all major manufacturers, directly flanged to the pump without additional couplings or guards. Covers made of stainless steel are available.
