Automatic Recirculating Valves

Pump protection valves ensure minimum flow through a pump. By doing so the pump is protected against overheating and cavitation which can cause damage.In case the process requires no flow or a small quantity of the pumped liquids, the pump protection valve automatically returns the required minimum flow via a bypass back to the pump.

Sealless Pumps

No mechanical seals: these cost-intensive wearing parts are cancelled by the seal-less method of construction, therefore optimal MTBF values (mean time between failure), reduced maintenance costs and long service life.
