Our general use oil is a higher viscosity vacuum pump oil designed for use with direct drive and belt driven rotary vane vacuum pumps. Through molecular distillation, lighter fractions are removed, resulting in lower vapor pressures and reduced backstreaming.
These properties allow the backing of diffusion pumps without the risk of contamination of the expensive diffusion pump fluids. Compared to other oils, the quality formula offers reduced maintenance costs, better pumping cycles, longer fluid life, and a cooler running pump. The economical pricing of our general use pump oil is also great for non-corrosive applications where frequent fluid changes are required.
Recommended to change pump oil every 3 months.
