Mobile phase delivery - Pistonmembrane

The piston-diaphragm pumps Wanner Hydra-Cell provide smooth pulseless flow in a wide range of flow rates and delivery pressure with high repeatability and accuracy and are ideal for dosing mobile phase into larger preparative units. In our experience these pumps are reliable and require minimal maintenance.

Wanner G03

G 03 pumpThe piston-diaphragm pump with anti cavitation system "Kell-Cell". Special system of channels equalizing pressure on both sides of the membrane which prevents cavitation damage of the pump. Stainless steel head and sturdy construction ensure long life and minimal maintenance costs, double hydraulically balanced diaphragm, piston sealing free design. Checking the oil level in the pump, followed by stopping the engine when the level drops to prevent mixing of oil into the mobile phase in the case of destruction of some of the membranes.

  • Smooth pulseless flow

  • Anti-cavitation system Kell-Cell

  • "Heavy Duty" design

  • Hydraulically balanced diaphragm on both sides

  • Wide range of flows and delivery extrusion heights

  • Repeatability and high accuracy - ideal for dosing

  • Piston sealing free design - minimal maintenance costs

Wanner G10

G10 pumpThe piston diaphragm pumps Wanner Hydra-Cell G10 with cam are used for different types of applications, usually involving liquids recycling. They provide smooth pulseless flow in a wide range of flow rates and pressures with high repeatability and accuracy and are ideal for dosing. Checking the oil level in the pump, followed by stopping the engine when the level drops to prevent mixing of oil into the mobile phase in the case of destruction of some of the membranes.

  • Smooth pulseless flow

  • Anti-cavitation system Kell-Cell

  • "Heavy Duty" design

  • Hydraulically balanced diaphragm on both sides

  • Wide range of flows and delivery extrusion heights

  • Piston sealing free design - minimal maintenance costs

The pumps are equipped with heads made ​​of stainless steel (AISI 316). They are suitable for temperatures up to 70 ° C. They are supplied with engine, clutch and durable metal frame for installation in industry. Both G03 and G10 pumps can be supplied also in a version for hazardous areas according to ATEX Ex de II T4.
