Welch Direct Drive Vacuum Pump

Designed for direct drive vacuum pumps this triple distilled hydrocarbon oil is derived from hydrotreated base stock for high performance in vacuum pump operation at elevated temperatures.

Welch direct drive vacuum pump. Welch premium vacuum pump oil resists breakdown in the high rpm operation environment of direct drive pumps. Our extensive portfolio includes diaphragm pumps rotary vane pumps piston pumps and turbomolecular pumps and systems in addition to a wide range of accessories. Welch premium vacuum pump oil resists breakdown during the high rpm operation of direct drive pumps. Direct drive pumps are not.

Vacuum system configuration with a cold trap is recommended for use with harsh chemicals. Three features drive these benefits. The crvpro family consumes up to 36 less oil than comparable pumps. Other direct drive rotary vane vacuum pumps.

Welch direct drive rotary vane vacuum pumps achieve vacuum levels down to 1x10 4 torr 0 1 micron with flows up to 11 3 cfm. The 8905a achieves 0 050 torr with a pumping speed of 51 liters min 1 8 cfm. The new crvpro family of direct drive vacuum pumps offers increased reliability and longer service interval vs. Two stage oil sealed vacuum pumps should not be operated continuously at pressures above 1 torr.

The welch 8905a direct drive vacuum pump is a robust vacuum pump for applications requiring pressures 50 torr. Runs 10 c cooler than comparable pumps. Chemstar belt driven vacuum pumps are designed to tolerate harsh chemical contamination. Three features drive these benefits.

Besides single pumps welch also offers complete oil diffusion pump systems. These small direct drive oil sealed vacuum pumps should not be operated continuously at pressures above 50 torr. Applied vacuum technology for laboratory and industry welch is a leading pump manufacturer of high quality durable vacuum products. Other direct drive rotary vane vacuum pumps.
