MICROVAC SERIES OIL SEALED ROTARY
PISTON PUMPS
In today's globally competitive environment, the need for manufacturing and process equipment delivers maximum performance and reliability is greater than ever. Whether you operate at low pressure, handle large gas loads, or simply need increased capacity for your existing system, BOC Edwards can help you meet your pumping requirements.
Solutions to fit your needs
Our total vacuum capabilities include a full line of pumping systems from 30 to 7880 ft3min-1 capacities. Choose from microvac rotary piston pump (H or J series), 1700 series high capacity packages., and 1800 series mechanical booster packages, or a custom designed package to meet all your pumping needs.
Features & benefits
• Rugged reliable operation - robust cast and ductile iron construction.
• Efficient design - provides maximum uptime with minimal moving parts and large clearance.
• Low ultimate blank-off - pressures down to < 10-2 Torr.
• Quiet operation-new valve design virtually eliminates valve maintenance and noise
• Space saving design - saves up to 50% of valuable floor space.
• Complete and self-contained - delivered and ready to install.
• Automatic lubrication - system provides proper flow of oil to bearings and sealing surfaces, prevents back flow into system.
H & J series overview
The J series microvac rotary piston pump sets the standard for performance and reliability as the industry's most efficient, space-saving design. The microvac rotary piston pump has been improved, upgraded, and finetuned
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 more stylized design for the J series. A larger oil sight glass and paddle wheel design flow indicator provides easier viewing of the oil system function.

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.
• Controlled balancing - reduces vibration to a practical minimum.
• Gas ballast- standard on all models
• Total capability - includes the manufacturing and service capabilities to keep your equipment in top operation - with a broad range of vacuum system accessories.
• Oxygen service models available.
