Piston pump
The piston pump is a hydraulically operated positive displacement pump that transfers mechanical energy as pressure energy. The piston pump has been designed with the aim of being the pumping solution for those processes where products with particles need to be pumped (fruit dices for instance) with a low shear rate. The principle of operation is based on the movement of a double effect piston which is powered by a hydraulic cylinder which provides the necessary power to move the piston. An open separator chamber seals off the product chamber from the oil system thus preventing any contact between the hydraulic oil and the product. The hydraulic cylinder is connected to a separate hydraulic power unit which gives the advantage that the pump can be located anywhere in the installation with the hydraulic power unit located remotely.

The piston pump is designed to operate in a wide range of applications due to the following features:
- It is able to pump products with particles (particulates) that are sensitive to shear stress (low shear rate)
- It is able to pump whole fruits and vegetables, slices and diced fruit
- It has a hygienic design
- It CIP cleans effectively
- Standard design temperature: 120 °C
- It can work under vacuum
Applications:
- Protein Industry
- Bakery and Confectionery
- Dairy
- Beverages
- Fruits and Vegetables
- Convenience food
- Pharmaceutical
- Personal care
- Environment
