INTENDED USE
Masport Vacuum / Pressure Pumps are intended to be used for loading and unloading of
liquid material. These pumps are commonly used for liquid waste transport, septic tank
cleaning, oil field service work, car wash or grease trap cleaning and many other
industrial applications.
WARNING!
Masport pumps must not be used to move flammable or highly
caustic material. Use of this pump for moving hazardous material
may result in machinery failure, bodily injury or even death.
SETUP
The 4-way valve on the pump is used to change the pump operation from vacuum to
pressure or pressure to vacuum by rotating the handle 90 degrees. Either side of the
valve can be plumbed as the intake or exhaust port. Depending on how it is plumbed,
the vacuum or pressure indicators on the top of the valve may be reversed.
When designing the system in which this Masport pump will be installed it is important to
make sure all of the components and plumbing are of adequate size.
NOTE!
Using components or plumbing with a smaller I.D. than
recommended for a particular pump will result in poor system
performance and may damage the pump.
The HXL75 model pumps are designed with 2 1/2" NPT ports. Any components, hose or
fittings with a smaller I.D. will restrict air flow and may damage the pump.
The HXL15 and HXL400 model pumps are designed with 3" NPT ports. Any
components, hose or fittings with a smaller I.D. will restrict air flow and may damage the
pump.
NOTE!
Before assembling the system, make sure the inside surfaces of all
pipes, hose and fittings are clean and free of any kind of dirt or
debris. Any solid particles ingested by the pump may result in
higher operating noise, loss of performance or irreparable pump
damage.
Some form of pipe sealant should be used on all thread connections to prevent leaks.
HOSE
Any hose used in your system should be rated for at least 28" hg vacuum and 25 PSIG
pressure. It will also need to withstand an oil/air mixture at temperatures up to 300° F.
"Hot Tar and Asphalt" hose is designed for use in this type of environment.
