Quincy QSV Series Vacuum Pump 7.5-200 HP

The Nuts and Bolts of the QSV Series

The Quincy QSV series offers a total vacuum package, complete with modulating inlet valve, control panel, electrical enclosure, gauges, and exhaust separation system. Put it all together and you'll have a system that will maintain your process vacuum levels for years - automatically. With pumping speeds from 155-3000 CFM, the QSV line is able to meet every process requirement.

QSV series pumps can be set to run continuously or on a start/stop basis. Our Demand-A-Matic control option allows you to run two, three, or four units on a rotating lead/lag basis, and a programmable timer ensures optimum cycling of the pumps. Standard equipment includes a power-on light, hour meter, vacuum gauge, separator maintenance gauge, and discharge temperature gauge. Each pump meets our highest quality standards before leaving the factory.

A Model of Efficiency

Because the QSV series requires no sealing water, users can realize substantial savings on water and sewer charges, as well as on power consumption. In many instances, the payback on the QSV can be as low as one year or less.

Virtually Maintenance-Free

While you're counting the energy dollars the QSV saves you, be sure to notice what you're saving in maintenance costs. Our efficient airend design and tremendously long bearing life beats rotary vane and other vacuum technologies hands down. Plus, a cushion of fluid seals the clearances between the two rotors and the housing, ensuring that the rotors experience minimal wear.

The bearing package on the QSV line was initially designed for a compressor, with cylindrical roller bearings on the suction side and two sets of tapered roller bearings on the discharge side (three sets on the QSVI). The comparatively light loads and the heavy-duty bearings translate into extended pump life.

The Quincy QSVB

• Belt-drive
• Five models to choose from
• Capacities from 155 to 371 ACFM
• Can attain base pressure of 29.9" Hg vacuum (.5 torr)

The Quincy QSVI

• Direct-drive
• Six models to choose from
• Capacities from 365 to 3000 ACFM
• Can attain base pressures of 29.9" Hg vacuum (.5 torr)

Both the QSVB and QSVI are available with air-cooling or water-cooling, with sound enclosures optional.

For sealing and cooling, all models are equipped with a fluid pump to ensure positive fluid flow to the rotors and bearing assemblies, and a removable filter to keep particulates and debris out of the fluid. Because of its superior vapor pressure characteristics and tolerance to harsh process environments, Quin-Syn fluid is included in all pumps.

The air/fluid separator element is accessible through a removable top plate for cleaning and replacing, and a fluid drain valve makes fluid changes easy.

To protect against process failure, all models have a high air temperature (HAT) shutdown device. In case of process failure or malfunction, the sensor automatically reads high air/fluid temperature on the discharge side, and stops the pump. The air/fluid reservoir has an ASME-coded overpressure relief valve for high exhaust pressure.
