Beta and Delta Pumps

Sening Beta Pump

Centrifugal pumps are the most commonly used type of pumps. The Sening® centrifugal pumps BETA and DELTA are designed for transferring low-viscosity mineral oils from fuel oil tank trucks. Their compact design enables installation on most vehicle chassis.

The pump is driven by the power take-off drive unit (PTO) mounted to the vehicle gear-box. A wide range of input gear ratios and impellers are offered to adapt the flow rates to the requirements of most fuel oil tank trucks. As an alternative drive, a hydraulic motor drive is available for both pumps (HY).
