Masport Vacuum Pumps INTENDED USE  Masport Vacuum / Pressure Pumps are intended to be used for loading and unloading ofliquid material. These pumps are commonly used for liquid waste transport, septic tankcleaning, oil field service work, car wash or grease trap cleaning and many otherindustrial applications. PRIMARY SHUT-OFF: Prevents liquid in the tank from overflowing into the system and entering the pump. Liquid entering the pump can damage or destroy the pump.  SECONDARY MOISTURE TRAP (SCRUBBER): Removes liquid still in the air stream after passing through the primary shut-off. The Scrubber should be drained after every load.  VACUUM/PRESSURE GAUGE: Required to properly monitor the performance of the system. It should be located between the Scrubber and the Pump (the clean side of the pump) to prevent gauge failure due to foreign material.  VACUUM RELIEF VALVE: Governs the operating vacuum level. It should be installed at the ...

Vacuum Trucks What are They and How Do They Work? Vacuum pump trucks are by definition vacuum tanks that are truck mounted or vac trailer mounted coupled with a high velocity vacuum pump that hydraulically load wet and dry material via vacuum hoses.  A rotary vacuum pump  is driven by a PTO mounted on the truck that sucks up either wet or dry material. The material is then transported and is either pumped out or the tank is opened for dumping. The vacuum unit is truck mounted or trailer mounted on either a single axle or quad axle. Some units feature positive displacement blowers that operate in extreme weather conditions including temperatures as low as -35°F. Vac truck manufacturers offer accessories such as core drills, water jetters or air compressors at the time of purchase or afterwards. A liquid vacuum truck’s primary purpose is to transfer liquid and sludge waste to waste disposal companies.  Applications: They are typically conf...

Inspecting A Vacuum Tank Vacuum tanks are subject to significant stress as you load and unload wastewater every day. Constant changes in pressure and vacuum, combined with the sludge, grit and other foreign objects passing through the valves, can weaken many points in the tank.  Therefore, it’s important to clean out the tank regularly, and go beyond your quick daily visual inspection. Here’s A step-by-step approach to a thorough vacuum tank inspection: To get started, check vacuum gauges to verify all the stored energy has been released. This means there is no pressure or vacuum stored in the tank. Be sure to put the pump into neutral to dump vacuum or pressure . You can also open the load valve to equalize the pressure and release stored energy. Before opening the man-ways, check tank gauges to be sure the tank is not under pressure or vacuum. Serious injury or death can result if this precaution is not taken. While most man-ways are operated manually, there are a ...
