POWERPOINT® MONOBLOCK ROTARY HIGH VACUUM PUMPS SINGLE & DOUBLE STAGE
PVP-1 and PVP-2 series direct drive single and double stage Rotary Vane type High Vacuum Pumps are the latest addition in already existing wide range of Powerpoint® Pumps. These are monoblock type directlycoupled to very reliable electric motors.
These are not only compact in design but are also unbelievably noisless, vibration free and light in weight and at the same time are capable of creating ultimate vacuum to the tune of 0.05 m/Hg with a charge of only a few grams of vacuum oil. A sleek but study handle is provided on their tops for lifting - a real boon for airconditioning and refrigeration mechanics for their outdoor jobs, service stations, and also for those who need high vacuum in their laboratories, plants and other host applications.

| Liquid Ring Vacuum Pumps |
 |
Liquid ring vacuum pumps are
of the postive displacement type . Service liquid is regulated and due
to the eccentrically mounted impeller, the service liquid is thrown
towards the periphery of the stator thus forming a sealant ring .Process
is trapped in this space between the impeller blades, compressed and
expelled in a continuous suction exhaust cycle.
|
 |
|
MATERIAL OF CONSTRUCTION:
Stainless steel 316/304 impeller and shaft
grinded all over. Tolerances is standard .All other contact parts in graded
cast iron.
|
|
Material of construction to be used as per customer requirement.
|
 |
- Silent and considerable vibration free running.
- Needs no silencer.
- Mechanical Seals balanced on computerised machine.
- Maximum vacuum using water as a sealant at 30°c and at sea
level conditions.Dual stage model will be 720mm Hg vacuum
- Negligible maintenance and easy overhauling procedures.
- Modification for use as compressor possible.

Liquid ring vacuum pumps for higher speed on request. |
* Capacity of Two stage pumps are for dry air and service liquid (water) at30°c
sea level conditions.
* We recommend to use two stage vacuum pumps for applications upto
24" Hp vacuum.
* Service liquid flows are approximate,exact quantity will be determined
by actual installations.
* Any change in the interest of technical development are reserved.
