OMAC Series BE Lobe Pump is a close-coupled pump with the motor mounted directly to the casing via an IEC flange. The series is derived from Series B. The casing is AISI 316L stainless steel; the rotors are bi-lobe only.
OMAC Series BE lobe pump: why a close-coupled design?
The drive is attached to the rear cover with an IEC flange via a hollow shaft. The pump and motor form one compact, lightweight unit without external rotating shafts. It is easier to clean.
The manufacturer recommends BE for lighter duties instead of Series B. The series is intended for users who need a lobe pump with a high sanitary level at a lower price. The operating principle, materials and certificates common to all series are described on the OMAC brand page.

A separate chamber between the casing and the support prevents contact between the product and the lubricant.
What versions does Series BE offer?
- Jacketed casing — for heating or cooling the product.
- Enlarged inlet port — for thick products fed by gravity.
- Bypass — relief valve against pressure peaks.
- Pump units with drive — with a bare shaft or assembled with a motor, on a trolley, with adjustable feet and a stainless steel motor cover.
Speed is varied by a mechanical or hydraulic variator or by an inverter built into the motor. A geared motor is used for constant speed. Control options: reversing switch, IP65 inverter or IP21 inverter cabinet for a remote signal.
Where is the OMAC Series BE lobe pump used?
For pumping liquid and viscous products where a compact unit, simple cleaning and moderate cost matter. How to select equipment for product viscosity is covered in the article “Filling lines: how to choose equipment for product viscosity”.
For back pressure up to 20 bar and special versions, choose Series B, and for EHEDG certification, F or C.
Selection and service from Steiner Ukraine
To select an OMAC Series BE pump, we clarify:
- the product, its viscosity and temperature;
- flow rate and pressure at the duty point;
- drive type: geared motor, variator or motor with inverter;
- control method and degree of protection;
- required options: jacket, enlarged port, bypass, trolley.
Based on this data, we determine the series, size, rotors and seals. This is followed by supply, service and spare parts. Steiner Ukraine has been operating in the industrial equipment market since 2006.
FAQ about OMAC Series BE pumps
How does Series BE differ from Series B?
The motor is mounted directly to the pump via an IEC flange, so the unit is more compact and has no external rotating shafts.
Which rotors are fitted in BE pumps?
Bi-lobe rotors only, made of AISI 316L or CY5SnBiM anti-friction alloy.
Can a BE pump be cleaned in place?
Yes. The smooth cover and recessed rotor nuts are designed for CIP cleaning and SIP sterilisation.
Is BE supplied with a motor?
Yes, with a bare shaft or assembled with a motor, inverter and trolley.
