Liquid Transfer Cargo Pump | STP

Maximum Flow Rate: 1050 l/min (63 m 3 /hr)
Maximum Pressure: 10 bar g (145 psi)
Drive Options: PTO, Hydraulic, Electrical, or (diesel) Engine

The STP rotary lobe cargo pump is specifically designed for the safe and quick unloading of tank trailers and containers. The STP pump design is ideal for the transfer of both foodstuffs and chemicals across a wide viscosity range, making it a flexible and versatile pump suitable for a wide range of purposes and applications.

Multiple Seal Options

STP pumps are available with a wide range of seal options. For foodstuffs (glucoses, fruit juice concentrates, butter oil, etc.) the optimum choice is the single O-ring seal, and for chemicals and solvents, a multiple lip seal arrangement is available. In addition, a range of mechanical seals are available where required. All seals can be fitted in the same pump geometry.

Enhanced Rotor Design

The design of the STP tri-lobe rotors and ports has been developed using Computational Fluid Dynamics techniques to provide a smooth, gentle pump characteristic which minimises agitation and degradation of the pumped media. This results in a quick and quiet discharge even with high viscous media.

Compact Build

The compact build of the STP results in a minimum required space for mounting. The pump is designed for universal mounting with three sides of the gearbox pre-drilled to accept the mounting feet. Combined with a robust gearbox design, the STP pump can provide discharge pressure of up to 10 bar.

Drive Options

STP cargo pumps are equipped with an internal spline shaft to fit a close coupled hydraulic motor. A plain shaft extension with key is available as an option where a direct coupled electric, diesel, or PTO drive is required.
