H/2H Rotary Piston Vacuum pumps

Introduction:

Rotary piston vacuum pump is a sort of vacuum production equipment suitable for pumping ordinary gases and a little condensable gas (for example, water vapor) with 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 booster vacuum pump and roots vacuum pump. Rotary piston vacuum pump can be used for a longer time than the sliding vane rotary vacuum pump.

Application:


Piston vacuum pump is widely used in photovoltaic industry, aviation, petroleum, chemical industry, pharmacy industry, vacuum heat processing, vacuum coating, ceramics industry etc.

Features and Benefits

Sealed    Bearings

Bearing life is enhanced by isolating them from harmful process grit and solvents. No center wall bearing enhances reliability.

Tough  Valve  Assemblies


Heavy duty studs, springs and wear plates are mounted to hardened steel seats designed to prevent broken springs from falling into the pumping chamber.

Internal  Sealing  Oil  Channels

Sealing oil enters the pumping chambers through internal channels rather than exterior piping that is prone to damage and leakage.


Metal  Belt  Guards

Steel construction enhances safety and durability.

Large Site Port

Large diameter glass site port with stainless steel bezel and o-ring seal makes checking oil level and condition easy.

Oil Flow Indicator

An oil stream splashes onto the site port ensuring easy verification even when oil is dark.

Redundant  Shaft  Seals

Redundant Viton shaft seals ride on hardened steel sleeves to guard against leakage.

Caged  Hinge  Bars

One piece construction enhances wear life.

Rugged  Construction

Body is constructed from chemical resistant cast iron

After Sale Support

Three Year Limited Warranty and Uptime program offer assurance long after the initial installation
