Selection of Vacuum Pumps
When selecting vacuum pumps there are a number of things to consider:

What is the maximum vacuum needed at the workplace? The flow of a pump varies as the vacuum changes. Careful selection give you the best performance at the least cost.
How long is the maximum vacuum required? Process cycle time? We can select a size of pump to match your roduction rate or use a larger pump to increase productivity.
What is the total volume to be evacuated in cubic feet per minute (CFM) or in cubic meters per hour ?
How much will the vacuum fluctuate over the entire process cycle? Use of vacuum switches can vary the vacuum over the cycle time.
Does the application have special requirements? Dry? Oil Sealed? Inlet filtration?

Pump Types

Oil Filled Rotary VaneVane :These pumps use oil to seal around the vanes to achieve vacuum to 0.5 Torr or 29.9 "Hg. Single pump capacities range from 1 to 460 cfm or 630 cubic meters per hour. Most common pumps for vacuum to 29.9 "Hg.

Laboratory Pumps: We have a two-stage oil rotary pump for vacuum to 15 microns or 0.015 torr. These pumps are quiet and efficient with flows of 1.5, 3, and 5 cfm. Complete with exhaust filter, switch, overload protection, and various inlet options.

Oil Free Rotary Vane: These pumps contain no oil in the pumping chamber and can achieve a maximum vacuum of 27.5 "Hg. They use a special composite vane to ensure close contact with the cylinder wall. Low maintenance with good vacuum.

Oil Free Piston: These pumps are smaller in capacity and use a special teflon PFTE ring with a reciprocating piston to generate a maximum vacuum of 29.13 "Hg depending on the model. These pumps have a flow of 2 to 8 cfm. Their compact size and weight make them ideal for many applications.

Liquid Ring Self-Contained: This patented liquid ring technology is used in many food applications where there is the possibility of water carry over into the pump. Vacuum to 28"Hg can be obtained. Able to tolerate highly moist air and water carry over.

Regenerative Blowers: These oil free blowers are very good for large flow and vacuum to about 200 inches H2O or about 14"Hg. Flow decrecaes as the pressure increases. High flow for maximum air velocity to suspend solids.

A vacuum system is often consists of:these options:

The vacuum pump. Often more than one is used to provide greater capacity for upset conditions, backup redundancy in case of a breakdown, and faster drawdown. Different types of pumps can be used such as a first stage roughing pump and a secondary blower for greater capacity at low vacuums.
Inlet process air treatment includes the inlet filter, knockout pot, storage tank, coalescing filters, temperature and vacuum gauges, any separation tank and liquid level controls.
Outlet air treatment including mist eliminators and sound attenuation if needed
Control panel including motor starter, pressure regulators, high amperage switch, temperature switch, low oil switch, purge cycle power failure, low vacuum alarms.
Piping for both the exhaust and inlet to ensure condenasation of vapours does not adversely affect the operation of the pump.

The VessVAC pumps are quality built with thousands of hours of reliable service in the most demanding applicatons. Using a proven design the reliability and durability are ensured with its integral exhaust filters, vibration isolators, and composite vane material for longer life.
We supply laboratory and medical systems that require backup units and special requirements.
DRY running vacuum pumps are available that do not emit any oil or particulate materials into the pressure, vacuum or exhaust air streams. Most dry systems operate at vacuum levels to 29"HG.
Oil sealed rotary pumps can provide exceptional service for vacuum below 29"HG.
