The installation and the Pump-Prime Mover alignment
• The base or platform on which the motor and pump are mounted should be sufficiently rigid. It should be a structure that minimizes vibration.
• Use a flexible coupling to connect the prime mover to the shaft of the pump whenever possible. (But the tire coupling should be avoided.) The shaft should be aligned within the recommended TIR (total indication reading) 0.05 mm tolerance. However, this may be affected by differences in the connection method and the type of coupling. In this case please contact us.
• Correct alignment is important because incorrect alignment of the prime mover and pump can cause shaft breakage, bearing heat and wear, oil leakage, pump noise anomalies, vibration and other problems.
• In principle, there should be no external radial or thrust loads on the shaft ends. If you want to use a belt, chain or gear coupling, please consult us.
Pipeline and filtration:
• Import suction pressure (gauge pressure)
For mineral oils, the appropriate inlet suction pressure is + 35 to -16.7 kPa, and for water glycol and phosphate fluids, the inlet suction pressure is + 35 to -10.1 kPa.
• The suction pipe flow should be kept between 0.5 and 1.5 m / s.
Use a 150μm filter tank filter (suction filter). Use a full flow filter of 25 μm or less or a bypass filter of 10 μm or less.
• Filter installation
When using an immersed tank filter, install a filter that is approximately 50 to 70 mm from the bottom of the tank to prevent contaminants from entering. In the case of large fluctuations in oil levels, the installation should be designed so that air does not enter the filter.
• Inhalation, return pipe
Determine the specified suction pressure and reduce the suction resistance as much as possible.
• If using large diameter pipes, try to reduce the number of bends.
• The suction port of the pump should be less than 1 meter from the oil level in the fuel tank.
• The end of the suction pipe should be larger than 50mm from the bottom of the tank.
• Air is easily sucked into the straw, so pay attention to the joints, etc.
These should be properly sealed because air ingress can cause abnormal noise, vibration and component damage.
• The end of the return line should always be below the oil level, regardless of fluctuations in the oil level.
• A baffle should be installed in the tank between the suction and return lines.
• Pumping and conveying with a flexible rubber hose instead of a steel tube will reduce vibration and help reduce noise levels.
• During initial system startup (and start-up after long-term storage), it may be difficult for the pump to draw fluid. Air can be vented from the system by pre-installing the bleed valve (ABT-03) or by loosening the fittings in the duct.
• The pump should be running without load during pump and pipe exhaust.
