Page 3: Installation
Installation BEFORE COMMENCING ANY WORK, READ THIS INSTRUCTION CAREFULLY! Design limitations and technical data for each pump are found in the Product description. Installation of an IMO AB ACE pump does not require special skills. However, these instructions presume that the work is carried out by experienced fitters. -
Page 4: Pipe Connections
Measures shall be provided to avoid accidental contact with the outer magnetic rotor. Pipe connections The pipe work shall be installed and supported so that no pipe stresses are transfered to the pump body. The pipe work should be tight in order to avoid leakage and infiltration of foreign particles and/or air. -
Page 5: Strainer
Strainer The pump has to be protected from foreign matter, such as weld slag, pipe scale, etc., that could enter the pump via the suction line. If the cleanliness of the system cannot be guaranteed, a strainer must be installed in the inlet pipe near the pump. -
Page 6: Gauges
Gauges Gauges for monitoring the pump’s working conditions are recommended. These gauges should be placed readable as close to the pump’s in- and outlet flanges as possible. On standard pumps, series ACE there are gauge connections for both in and outlet. Pressure relief valve All systems with screw pumps must be equipped with a pressure relief valve installed immediately adjacent to... -

Start-up Before starting After installation and whenever it can be assumed that the pump has been emptied, the pump must be thor oughly filled with liquid. See fig 11. Make sure the prime mover is locked out and can not be started accidentally. Rotate the shaft by hand while filling the pump, to ensure that the rotor bores and magnetic couplings are Fig. -

Page 13: Service And Maintence
Service and maintence Service intervals The intervals for inspection and replacement of wear parts vary greatly with the properties of the pumped liquid and can only be determined by experience. Pumping liquid which contains abrasive materials, or liquid that is corrosive, will significantly reduce service life and call for shorter service intervals. -
