The Masport HW-Series Liquid Cooled pumps are designed with a water jacket around the cylinder to remove excess heat during heavy duty operation and to warm the pump prior to start up during cold weather conditions.
4-way valve to allow both pressure and vacuum operation. An example of an installation using a Masport Four Way Remote Valve is shown in the INSTALLATION DIAGRAM 90414 on page 25.
IV. DRIVE SYSTEMS HORSEPOWER REQUIREMENTS When selecting a drive system for the pump, it is first necessary to determine the maximum vacuum level the pump will operate at, if it is to be used in a vacuum only operation, or the maximum pressure level if the pump is to be used for pressure only or vacuum and pressure operation.
The most common type of belts used to drive this type of equipment are the standard B section and the BX sometimes referred to as cog belts. Other possible belt drive options are the 3V and 5V type drives. A 3V or 5V drive is desirable on systems requiring greater amounts of horsepower to be transferred on installations where spare for large diameter pulleys is not available.

more than a four groove pulley with B or BX type belts, six grooves on a 3V drive, and no more than four grooves on a 5V drive. The outside diameter of a B section pulley is the pitch diameter plus .35” PULLEY DIAMETER SELECTION - STANDARD B SECTION DRIVES NOTE: The horsepower figures HORSEPOWER...
3.) Pulley Horsepower Transfer Requirements Equation The first step in the design is to determine the design horsepower requirements of the pump being driven. A = Maximum Horsepower Required by the Pump B = 1.3 Service Factor C = Design Horsepower A x B = C Example: A HXL15WV is to be run at 1350 RPM and at 20 psi.
This is an important feature of the Masport Pump in that it allows the pump to be direct driven from the truck PTO without damage to the end cover or rotor due to loads...
NOTE: Installation of a Masport pump on a PTO system without the use of a telescopic joint in the interconnecting drive shaft will result in damage to the PTO, pump or both from excessive loading by the drive shaft.

Each liquid cooled Masport pump is shipped with a thermometer kit to monitor the coolant temperature out of the pump and the hose fittings necessary to connect the pump water jacket to 5/8”...

If the Masport pump is to be hydraulically driven, driven with an air cooled engine, or for some other reason the installation will not allow the pump cooling jacket to be tied to the engine cooling system, Masport provides a self contained cooling system for the HW- Series pumps.
Doing so will restrict the airflow of the vacuum pump. When selecting the type of hose to use, keep in mind that the Masport Pump is capable of up to 28” Hg and 30 PSIG. It is therefore important to select an interconnecting hose rated for full vacuum service and adequate pressure.
To avoid this condition, Masport recommends that “Hot Tar and Asphalt Hose” be used on systems intended for pressure and vacuum operation. “Hot Tar and Asphalt Hose” is designed for use with oil and high temperatures and has a life expectancy far beyond that of standard suction hose.
On systems where vacuum loading and pressure off-loading is desirable, but available space will not allow the use of a pump equipped with an integral valve, the Masport remote four way valve is a possible solution. With on side of the valve attached to the exhaust side, the mode of operation can be changed from vacuum to pressure by simply turning the selector lever on the valve.
5” Hg or 2 1/2 PSIG. Due to the high air flow capacity of the Masport HW-Series pumps it does not take long for a tank to reach these levels and is therefore not a problem.
When selecting a lubricant, the weight should be approximately a 30 weight for summer use and 10 to 20 weight for cold weather operation. If there is not a local source for acceptable lubricant, Masport supplies approved Rotary Pump Oil. Masport Rotary Pump Oil is available through the local Masport Representative...
If Rotary Pump Oils are not available in the immediate area, a high quality, non-detergent, straight weight diesel engine oil is an acceptable compromise but will not produce the same results as the Rotary Pump Lubricants. LUBRICANT FLOW RATE 1.) Pump Pressure Actuated Lubricator On systems equipped with Pump Pressure Actuated Lubrication, the lubricant flow rate is regulated in part, by the vacuum or pressure level the pump is operating at, and in part by the setting of the needles on the sight feed valves.
Masport Pressure/Vacuum Pumps. All necessary components that comprise a reliable Vacuum or Pressure/Vacuum System are listed below with their Masport part numbers. We feel the Masport Components are the finest available to protect the pump and provide a reliable, profitable pumping system.
2.) Do not operate the pump during the drive to the job site as the RPM at the pump could be abnormally low or high. 3.) Make frequent checks of the oil level in the tank and the oil flow rate at the sight feed valves.
To eliminate buildup of foreign material on the inner working surfaces of the pump and ensure smooth operation and maximum pump life, it is recommended the pump be flushed with Masport flushing fluid daily, preferably at the end of the workday. Flush the pump more often if carry-over from traps contaminate the pump.
If the vanes are worn to the point that they need to be replaced, it may be time for the bearings and oil seals to be replaced also. If this is the case, Masport offer Repair Kits for pumps that require replacement parts, but are not worn badly enough to require boring and honing.
* Monolec Compressor Oil is colored red and should not be confused with transmission fl uid. These oils have been approved for use in Masport Vacuum/Pressure Pumps. Use of these oils will extend the life of the vacuum pump and ensure proper performance and lubrication.
