The Stokes Microvac has stood the test of
time to be the most efficient and reliable rotary piston pump. Now improved, upgraded and fine-tuned, the
new ‘J’ series promises to deliver optimal performance with minimal maintenance
and low operating costs.
The current ‘J’ series leverages decades of
engineering design evolution to deliver reduced noise, improved sealing and a
robust performance, with minimal maintenance and low operation cost.
The Stokes Microvac pump from Edwards is a
self-contained, oil-sealed rotary piston pump, with low rotation and large
clearances to achieve a longer life cycle. A new encapsulated valve design,
improved O ring sealing areas and a totally enclosed fan cooled motor ensures
lower noise, lower power and extended service intervals for customers. The slow
rotational speed reduces wear on the piston and slide components for longer
life and offers greater ability to handle particulate applications.
integral oil distribution system eliminates external piping and provides
leak-free operation in a stylised design. The pumping piston is mounted to the
main drive shaft via an eccentric and supported by two free oscillating hinge
bars. When the piston rotates, air enters the pump through the piston slide. As
the piston reaches the top-centre position, the intake port is closed,
compressing the trapped air, which is discharged through the exhaust valves and
out of the reservoir exhaust outlet as the piston continues to rotate.
Performance speaks for itself; Stokes
Microvac remains favourite for a broad range of processes including extremely
harsh duty applications.
