Liquid linear pumps work by reduction of a volume by direct action of a shuttle on a diaphragm.
- Very long life
- Low noise level
- Low power consumption
- Low pulsation
- High efficiency
- No bearings
- Flow rates up to 0,01 cfm (300 ml/min), suction height up to 8.7 psi (3 mH2O), pressure height 26 psi (9 mH2O)
Liquid linear pumps utilize electromagnetism to apply force to a diaphragm positively displacing liquid. Alternating current in electrical coils reverse the magnetic field induced around a magnetized rod at a rate determined by the supplied frequency. Movement of the diaphragm attached to the end of the rod forces the medium through one-way valves.
Linear pumps are quiet and efficient. With fewer wearing parts than equivalent reciprocating devices, linear pumps are regarded as long life, low maintenance devices ideally suitable for low differential pressure applications.
