OMAX High-pressure Pump
The OMAX variable speed, high-pressure pump is an electrically driven, variable speed, positive
displacement, crankshaft drive triplex pump designed for use with the OMAX Precision JetMachining
system and other applications requiring high-pressure water. This pump provides the high-pressure
water required by the OMAX JetMachining System to operate.
Figure 2-1: OMAX High-Pressure Water Pump
The pump’s major drive components include the variable frequency drive (VFD), the main electric motor, the
belt drive between the motor and the pump, and the crankshaft drive for the high-pressure pump. The
electronic VFD varies the electric motor speed, and therefore the pump speed. The variable frequency drive
accommodates slight variations in nozzle flow characteristics, produces surge free starting, and provides
high power factors and VFD/motor efficiencies throughout the useful power range.
Pump components are mounted in a compact enclosure that occupies only 15 square feet (1.4 square
meters) of floor space. All electrical control components and the VFD are located in the electrical enclosure
mounted on the end of the pump unit (Figure 2-8).
The main electric drive motor, belt drive, and OMAX high-pressure crankshaft are mounted on a welded steel
tray that is mounted in the steel pump frame with anti-vibration mounts. A water module is mounted on a
steel tray and consists of a water tank and charge pump.
Removable covers are provided on the front and back, and on the left-end of the pump unit. The pump’s
laminated wood top can be raised, allowing easy access to the water filters and pump high-pressure wet-
end.
A charge pump is responsible for the pre-circulation of water through the pump’s white water tank and
cooling lines. This flow purges warm water from the water tank and the pump cooling lines before the high-
pressure pump starts. Cooler water increases the life of the high-pressure pump seals. This water is then
recycled back to the white water tank.
