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.
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.
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.
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.
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.
ATEX compliant version available to ensure safe handling of explosive material and hazardous chemicals.
The STP is suitable for CIP (Cleaning in Place) and SIP (Sterilisation in Place) and is certified to 3A and FDA standards, offering customers reliable and highly sanitary pumping conditions.
The STP pump design has been optimised specifically for applications within the road tank industry, providing low pulsation and low shear handling of sensitive products, reducing the risk of product damage and thereby improving product quality.
The rotor case can be inverted, where required, adding flexibility to the port arrangement.
On request the pump can be supplied with sealed heating tanks for safe and reliable handling of delicate, temperature sensitive products.
The STP pump’s advanced technology and engineering provides smooth flow, reversible operation that is reliable and efficient.
The STP compact pump build combined with a robust gearbox design provides for discharge pressure of 10 bar and for temperatures up to 70˚C (or at 130˚C for CIP/SIP).
STP stainless steel rotary lobe cargo pumps have been specifically designed for applications within the liquid transfer industry for road tankers. Suitable for handling a wide variety of liquid types, STP pumps provide hygienic performance for:
