Remote Head Designs for LEWA pumps.

LEWA remote heads — Introduction LEWA remote heads. Disconnecting from the displacement system for more safety. Certain process engineering applications require fluids to be metered, conveyed or circulated at extreme temperatures, also in conjunction with high abrasiveness or toxicity. To protect the operating personnel as well as the system, it is frequently necessary for these critical areas to be disconnected from the displacement system of the pump. LEWA has developed a solution for such applications in which the valve head is spatially separated from the displacement system of the pump....

LEWA remote heads — Advantages LEWA remote heads. The advantages at a glance. Conveying extreme and hazardous fluids If fluids with an extreme temperature, high abrasiveness or toxicity have to be metered, LEWA remote head designs are used. These disconnect the critical areas from the displacement system of the pump. The displacement movement is transferred by what is called a "hydraulic link". Hermetically tight Diaphragm pumps work without dynamic seals due to their design. This creates a hermetically tight working area. There are no spillages to the atmosphere and contamination of the fluid...

LEWA remote heads — Pump heads Pump heads for extreme requirements. Possible versions of the remote head design: – isplacement system and valve head with a packed plunger or diaphragm design D – alve head is positioned geodetically higher or lower than the displacement system V – ydraulic link is furnished with a cooling jacket H Remote pump head MV. Elevated valve head for extremely high temperatures. Pipe connection for the discharge side Valve head Hydraulic link (reciprocating line) with process fluid Suction and discharge check valve Pipe connection for the suction side Cooling/heating jacket...
