It should be noted that the above table is simply a recommendation and that the correct Masport Pump should be selected based on your specific application. To ensure that the correct Masport Pump is selected please contact an authorized Masport distributor or Masport directly.

Rotary Vane Vacuum Pumps require a high quality non-detergent Rotary Compressor Oil or Rotary Turbine Oil. Oil specifically formulated for Masport pumps is available from your local Masport representative or by contacting Masport Inc.

Masport Pumps can be run either under continuous or intermittent vacuum. As the name states, intermittent vacuum allows you to operate the pump at high vacuum for short periods of time. For longevity and durability it is recommended to run Masport pumps at or below the continuous vacuum levels. For Masport Pumps the maximum continuous vacuum level is as in the table below:

PumpMaximum Continuous Vacuum Level  at Sea Level (“Hg)
HXL2V20
HXL3V20
HXL4V20
HXL75V20
HXL75WV25
HXL400WV25
Viper22
Titan22
Sidewinder22
Hydra25

It should be noted that the maximum continuous vacuum level can be affected by the following variables:

  • Operating at elevated height above sea level – the vacuum level decreases ~1” Hg for every 1,000 feet of elevation
  • Operating in condition of high ambient temperature
  • Operating RPM of the pump

To ensure that the correct vacuum level is setup for you pump please contact an authorized Masport distributor or Masport directly.

The cooling method of a pump dictates the level of continuous vacuum that a pump can operate at. For Masport Pumps the following continuous vacuum levels can be achieved for the different cooling methods:

Cooling MethodContinuous Vacuum Level at Sea Level (“Hg)
Air20
Fan22
Water25

Higher levels of vacuum are typically required for the following:

  • Deeper lifts – the distance you can move product from below ground level
  • Operating at elevated height above sea level – the vacuum level decreases ~1” Hg for every 1,000 feet of elevation
  • Operating in condition of high ambient temperature

Masport vacuum pumps require little regular maintenance except for flushing the pump. This should be done weekly or anytime liquid or solids have been allowed to enter the pump. Flushing Fluid specifically formulated for Masport pumps is available from your local Masport representative or by contacting Masport.

Masport Pumps should be inspected for vane wear at least once a year. If vane wear is not monitored, the vanes can become too short causing excessive rotor and cylinder wear and eventually result in vane breakage.

Measure the vanes to see if they are within the usable limit. If they are not they should be discarded and replaced. The vanes should be replaced when their height is below the usable limit detailed in the table below:

PumpVane Useable Height
HXL2> 1 5/8”
HXL3> 1 5/8”
HXL4> 2 1/4″
HXL75> 2 5/8”
HXL400> 2 3/4”
Viper> 2 5/8″
Titan> 2 1/8”
Sidewinder> 2 1/8”
Hydra> 2 1/8”

Yes! In order to operate efficiently and at their best, vacuum pumps rely on heat radiating to keep them cool. If mud or debris becomes packed on and around the vacuum pump the heat has trouble escaping and the performance becomes limited.

To keep the pump in a workable condition operators should undertake regular maintenance and keep a written log of those checks.

Before Starting:

  • Ensure a vacuum relief valve and a pressure relief valve are installed in the system and adjusted to recommended settings, taking into account the altitude of the job location.
  • Always bleed the tank to atmospheric pressure before switching the valve from vacuum to pressure or from pressure to vacuum.

Every Load:

  • Drain the scrubber after each tank load. If nothing drains when the ball valve is opened never assume it is empty, check for a blockage in the valve.
  • Check the oil level in the oil reservoir and fill as required.
  • Monitor vacuum/pressure and temperature gauges to detect any irregularities or problems.

Daily:

  • Add oil approximately every 10 hours of operation or when the oil reservoir shows the level is low. Only use approved lubricants.
  • Drain the oil separator twice daily. A brass ball valve is mounted at the bottom for easy draining.

Weekly:

  • Flush the pump weekly with Masport Flushing Fluid, or any time that liquids or solids have been allowed to enter the pump.
  • Check and clean the Inlet Filter. Ensure the filter is completely dry before refitting. This checking process must be done any time contamination may have entered the system.
  • Check to ensure the pump RPM is within the recommended range. Running the pump too fast or too slow may cause damage.
  • Wash any dirt off the pump as it needs to be clean to allow heat to radiate and prevent it from overheating.

Annually:

  • Check bolt mountings, drive coupling alignment and condition, and vane wear.

Storage:

  • If the pump is to be sitting for an extended period of time it needs to be flushed prior to storage. After flushing, pour oil into all bearing lubrication ports to protect the bearing surfaces and oil injection points on the pump to eliminate rust formation on the rotor and cylinder.
  • Rotate by hand monthly to distribute oil.
