Stokes Microvac 912J
MODEL AKTUALNIE WYCOFANY Z PRODUKCJI na rzecz nowych pomp suchych GXS
The Stokes Microvac rotary piston pump sets the standard for performance  and reliability as the industrys 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. In addition oil temperature/heater  ports have been added as standard to provide a means to monitor and heat  the pump oil if required.
