LEWA offers the most advanced pump technology in the world. Lewa diaphragm metering pump heads in particular are not only extremely efficient with their patented technology, they are also cost-efficient and safe at the same time.
For fluids of any kind
Pump head design options
Special materials by customer request, for example 2.4610, titanium, plastics
Diverse connection geometries
CIP and SIP capability
Heating and cooling jacket
Fully heated pump heads (including valves) for melting
Remote head design for extreme temperatures
Pump head M500 – universal applicability for large flow rates
The LEWA M500 is a pump head with a hydraulically actuated diaphragm made of pure PTFE for universal use. It is mainly used for large flow rates on LEWA process pumps.
The multi-layer diaphragm (also called sandwich diaphragm) separates Chambers A and B and is simultaneously used to seal Chamber A and B from the atmosphere. Since it is a static seal, the pump head can be considered hermetically sealed. The condition of the multi-layer diaphragm is monitored continuously. Chambers B and C are separated by a piston and multiple hydraulic valves.
Pump head M900 – the pump head for medium flow rates
The LEWA M900 is a pump head with a hydraulically actuated diaphragm made of pure PTFE with a diaphragm holder made of stainless steel. It is designed for universal application. It can be used on all LEWA ecoflow pumps and with average flow rates on LEWA process pumps.
Pump head M800 – reliable at high pressures
LEWA Series M800 diaphragm pump heads are, in principle, designed like the pump heads of the tried-and-tested M500 series. These are pump heads with a freely oscillating PTFE diaphragm and diaphragm position control via a control push rod.
The special feature of this series is the very high level of permissible operating pressure. Pump heads of the M800 series can be used for discharge pressures up to 1000 bar.
Pump head M200/M400 – stainless steel diaphragm for special requirements
The LEWA M200/M400 is a pump head with a hydraulically actuated diaphragm made of stainless steel (or of other high-quality materials like Hastelloy or titanium). It is used in places where diaphragms made of plastic can no longer be used:
Extremely high operating pressures possible
Extremely high operating temperatures possible
Pump head K110/K111 – K210/K211
The piston displaces the conveyed fluid directly in plunger pumps. Pistons and plunger seals are wetted. A high degree of operational reliability is achieved as a result of the suitable piston materials and seal design.
Durable and simple structure
High metering accuracy
Long piston service life and plunger seal due to movable pistons and the selection of material for each individual application
LEWA piston pump heads require only low maintenance effort
