The Stokes Microvac rotary piston pump sets the standard for performance and reliability as the industries most efficient, space-saving design. The Stokes Microvac rotary piston pump has been improved, upgraded, and fine-tuned to deliver even better dependability and productivity combined with minimal maintenance and process downtime.
An integral oil distribution system eliminates external piping and delivers leak-free operation in a stylized design. A stiffer motor mounting platform cuts flexibility to minimize motor belt wear. A stylized oil reservoir cover and side cover ‘O’ rings improve sealing to eliminate oil leakage. An integral gas ballast valve built into the side cover allows quick adaptation to automatic gas ballast.
Most importantly, these improvements don’t increase the industry leading space saving footprint. Inlet, outlet and mounting dimensions are exactly the same as the H series Microvac rotary piston pump.
This pump is fitted with a 230/460V coil for control of the oil solenoid valve which prevents the pump from flooding with oil in the case of power failure or a loss of vacuum.
The Microvac 212J pump is a self-contained, rotary, oil sealed piston type unit. 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-center position, the intake port is closed. The entrapped air is then compressed and discharged through the exhaust valves and out the reservoir exhaust outlet as the piston continues to rotate.
Lubrication of the internal components of the pumps is completely automatic. This pump is fitted with a 230/460V coil for control of the oil solenoid valve which prevents the pump from flooding with oil in the case of power failure or a loss of vacuum.
To allow pumping of high vapor loads, an integral gas ballast is fitted. This is used to prevent condensation of the vapor carried by the pump gases.
