BCF - Flexrod design

Food and hygienic pump with joint-free, flexible titanium shaft

The BCF food and hygienic pump from SEEPEX, with its joint-free, flexible titanium shaft (Flexrod) is certified under 3-A Sanitary Standards. Tangentially positioned flush connections allow residue-free cleaning in CIP and SIP processes. Optimal cleaning and sterilization can also be achieved when disassembled (COP). Thanks to minimal pulsation and shear characteristics, it is particularly suitable for conveying of sensitive food.

Features and Benefits

Fulfills strict hygienic standards

Certified under 3-A Sanitary Standards; the Flexrod additionally fulfills the highly demanding EHEDG requirements and utilizes FDA-approved components

Low pulsation

Minimal pulsation and low shear characteristics allow the transport of sensitive products – even containing whole pieces

Residue free cleaning

Thanks to special housing geometry, joint-free Flexrod and tangentially positioned flush connections: CIP, SIP, COP

Service-friendly

Low space requirements and no special tools required for maintenance – simply release the Flexrod from the rotor and drive shaft

Process-optimized

Low cleaning costs and reduced production facility downtime due to quick and simple maintenance

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.

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.

Standard base plate

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

Pressure branch

Made of stainless steel, with internally polished finish and externally satin finish. Allows effective draining. Connection: pipe coupling to DIN, Tri Clamp® or any other known sanitary fitting.

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.

Conventional geometry

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.

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.

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.

Flexrod

A flexible titanium shaft absorbs the rotating movement: the pump does not need any joints. A flexrod is particularly suitable for hygienic pumps, such as the BCF and BCFH range.

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.

Base plate

Made of stainless steel, glass bead blown. For the support and attachment of the pump.

Mechanical seal

Flushed by the product and located inside the suction area for optimal cleaning.

Open pin joint

Newly developed hygienic joint, designed for higher pressures and flow rates.

Suction pipe

Available in DIN, Tri Clamp® or any other known sanitary fitting.
