Membrane and Piston Pumps
GRUPA WOLFF is a distributor of membrane pumps and piston pumps.
Inner parts of the membrane pump drive have no contact with the product since they are separated from it with a membrane. Therefore, the pumps are frequently applied at transport of slurry and of polluted, erasing or corrosive products.
Piston pumps are used for transport of condensed, dehydrated slurries and pastes and wherever high pressure is required.
We offer a selection of a proper pump, installation works in a full extent, commissioning and service of the already installed equipment. Our offer also includes original spare parts for membrane and piston pumps.
1. MEMBRANE PUMPS
DESCRIPTION WITH BASIC PARAMETERS
Inner parts of the pump drive have no contact with the product since they are separated from it with a membrane. Therefore, the pumps are broadly applied at transport of slurry and of polluted, erasing or corrosive products. Depending on the type and material design, the maximum delivery is 800 m3/h and the maximum pressure – 25 MPa. All pumps are powered by electricity.
SCOPE OF DELIVERY
- EM electromechanical membrane pump
- CM membrane pump with a double membrane
- HM membrane pump with an increased-strength formed membrane
OPTIONAL IMPLEMENTATION
- Design for operation in an explosion risk zone (ATEX).
APPLICATION
