Pump Performance

Manufacturers offer technical advances to keep vacuum maintenance down and your profits up

Whether you’re emptying a septic tank, servicing a restroom or providing countless other services, the key to every pumping job is the pump itself. No go means no dough.

But dependability, reparability and recovery are only a few of the important features to consider when shopping for a vacuum pump. Should you go

liquid-cooled or opt for big air? And would a remote switch increase productivity?

As the busy summer season winds down, here are a few pumps and technologies from the industry’s top manufacturers to consider as you look to update or expand your fleet.

Liquid Cooled

The liquid-cooled HXL400WV vacuum pump from Masport Inc. delivers 400 cfm of air flow with an operating range of 1,000 to 1,275 rpm. Weighing 450 pounds, the pump is capable of achieving 27 Hg intermittently and 25 Hg continuously at sea level. In pressure mode, the pump will produce 30 PSIG intermittently and 20 PSIG continuously. Engineered for fast load times and optimum recovery, a water-stabilized cylinder allows higher continuous vacuum and eliminates freeze-ups during the winter months. The mechanically driven oil pump ensures correct oiling with no adjustments needed. The integral four-way valve is designed with a self-adjusting, spring-loaded spool to eliminate leakage through normal wear. Easy to service and rebuild, the pump features a double-end shaft to accommodate clockwise and counter-clockwise rotation drive systems. Each pump also comes with a vacuum relief valve. Forged high-tensile hub shafts with integral bearing jacking screws, Viton O-rings and shaft seals come standard. For more information: 800/228-4510; www.masportpump.com.

Shorter Recovery

The air-cooled PM100 dual fan, rotary vane vacuum pump from Moro USA is capable of producing 460 cfm free air, 29 psi and 22 Hg of continuous vacuum. Even at 15 Hg, the pump will produce 388 cfm. Rotating at 1,500 rpms, the pump’s beefy rotor, six Kevlar vane construction and high-performance oil pump add up to shorter recovery times. Its compact design also facilitates easier installation.

Remote Switching

The Conde Activator from Westmoor Ltd. works with the Conde Slide Valve for remote switching of the pump from vacuum to pressure mode or pressure to vacuum. The Activator switch can be mounted in almost any location for easy access. A remote-control fob is available. The actuator motor is built to withstand the harshest environments, while its compact design enables it to fit almost anywhere. The Activator is available for all Conde Slide Valve pumps, including the Super 6, SDS 6 and SDS 12, and can be used on gasoline and diesel-powered units, right-angle drive units or any other pump/drive configuration.

Air Cooled

The RCF 500 heavy-duty, air-cooled vane vacuum pump from Fruitland Tool & Mfg. is designed for continuous duty and reduced downtime. The 350-cfm pump (1,400 rpm) has eight vanes and close tolerances for optimum performance. A positive displacement oil pump requires no maintenance or adjustments, and precisely delivers the correct amount of oil to each of four locations for minimal oil consumption. Heavy-duty roller bearings and a self-centering rotor allow for quiet, efficient operation. The cooling system incorporates a high-flow fan and shrouded housing that ensures low pump temperatures for all applications and environments. The unit also features easily accessible vane checkpoints and an integral stainless steel filter option that works on both vacuum and pressure to keep debris from entering the pump. Options allow for any mounting or drive configuration. The 450-pound pump provides 320 cfm at 18 inches Hg with pressures to 30 psi. For more information: 905/662-6552; www.fruitland-mfg.com.

Big Air Series

Available in 700, 900 and 1,400 cfm, the High Vacuum Blower series from National Vacuum Equipment utilizes air-injection through an internal manifold system, enabling each unit to perform continuously at maximum volume. Featuring a heavy-duty noise dampening housing with multiple bolting locations, packages include four-way valve for vacuum and pressure operation, 2:1 gearbox, intake and ballast filters, ballast and intake check valves, and pressure relief (10 psi). The 747 model delivers up to 647 cfm (454 cfm at 18 Hg) at 4,200 rpm. The 957 offers 1,007 cfm (669 cfm at 18 Hg) at 3,600 rpm, while the 1457 provides up to 1,546 cfm (1,188 cfm at 18 Hg) at 3,600 rpm. For more information: 800/253-5500; www.nvepump.com.

Tireless Workhorse

The Wallenstein 753 air-cooled pump from Elmira Machine features close machining for efficient high vacuum. Weighing 340 pounds, the 350-cfm pump with 27 Hg maximum vacuum has extra wide, heavy duty rotor vanes for lower maintenance and less downtime, low rpm operation (1,150 rpm) for quiet operation and easy internal access. For more information: 800/801-6663; www.elmiramachine.com.

Blower Package

The Jurop PVT200 tri-lobe blower package from Chandler Equipment Inc. is designed to deliver top performance without maintenance. Providing maximum speed at 1,500 rpm, 795 cfm and 27 inches of continuous duty vacuum, the positive displacement rotary lobe pump features profiled and synchronized cast iron lobes. The Suction Group includes inlet and outlet silencers, air-controlled four-way changeover valve, final filter, non-return check valve, flanges and bolt package. PVT Series blowers are oil free and environmentally safe. No lubrication is needed within the pumping chamber since the pump works without friction, consequently there is no oil delivered to the atmosphere.

Heavy-Duty Application

The Premium 250 Series centrifugal pump from Dragon Products Ltd. features a 35 percent thicker concentric housing for extra strength and extended service life. The open-vaned impeller is designed to reduce turbulence, eliminate recirculation, lower radial and thrust load, and provide a smooth flow of liquids. The larger diameter shaft delivers heavy-duty performance with minimum deflection. The heavy-duty outboard bearing assembly consists of a pair of angular contact bearings with high thrust load rating and zero end play. The heavy-duty inboard bearing is a double row ball bearing with high radial load rating to compensate for the larger size impeller and heavy-duty applications. The oil bath lubrication system is designed with a larger oil reservoir that provides free circulation and better heat dissipation for longer bearing life.
