Piston pumps VPModel VP 25D, VP 40, VP 90S, VP 120P, VP 120S
Characteristic:
- not required operation liquid - oil-free operation
- the pumps reach deep vacuum
- low noisiness
- compact construction
- low weight
- do not contaminate the transported gas
- easy installation
- low temperature at the pump head
- long life-time
Applications:
- printing industry
- food industry
- packaging industry
- laboratory and medical equipment
- automation
Principle:
The basic principle of the piston pumps is based on linear reversible movement of the piston (1) in the cylinder (2). The piston is moving by piston rod (3), which is driven by the winch by force of cam mechanism (4) – conversion of rotary motion to linear. The piston is sealed towards the cylinder by the piston ring (5), which has high thermal conductivity and low friction without need to lubricate it. By movement of the piston in the cylinder downward the air is sucked through a one-way suction valve (6) into the compression chamber. By movement of the piston upwards, the air is pushed away by the one-way exhaust valve (7).
