Rotary Piston Vacuum pump

Model:2H-70C


Here are two kinds of the rotary vacuum pump: model H single-stage rotary piston vacuum pumps and model 2H double-stage rotary piston vacuum pumps. Rotary piston vacuum pump is a sort of vacuum production equipment suitable for pumping ordinary gases and a little condensable gases (for example, water vapour) with a gas ballast used. The pump must be fitted with appropriate accessories if gas is rich in oxygen, explosive, corrosive to ferrous metal, chemical reactive with vacuum pump oil. The pump can be operated singly. It also can be as a backing pump when combined with another high vacuum pump, such as diffusion pump, oil booter vacuum pump and roots vacuum pump. Series rotary piston vacuum pump can be used for a longer time than the sliding vane rotary vacuum pump. It is widely used in vacuum coating, vacuum heat treatment, vacuum sintering, molecule distilling and simulation testing, etc.

Features:
●Low vibration, low noise by optimizing design and matching weigh
●Supply oil singly to baring seal house, because the baring seal house and the pump house is be fenced out, it is avoided that the impurity come into the baring seal house, that beget the baring and seal to be shattered prematurely.
●According as the consumer requisition, the subsidiary oil box can be equipped, it can make the oil cooling and the impurity separating.
●The motor is on top of the pump besides the old model H-150. Compact structure, fewer dimension control clearance.

Explain:1、1401*、H-7*、H-8A* are old pump
2、Hereinbefore,ultimate pressure is partial ultimate pressure that is measured by compression gauge.
