Page 5: Introduction
3.2 - PIPING SYSTEM 1 - OMAC pump suction and discharge are sized to suit passage of even very viscous medium; consequently the piping should not be necessarly proportionate to them. 2 - The suction and discharge piping should be sized according to the calculus in the technical handbook, considering the expected capacity, viscosity and friction losses. -
Page 6: Piping System
4 - The pump should be installed near the source, from which it sucks. 5 - Reduce at min. bends and necks along the whole line. 6 - Use large radius bends, avoiding Tees and needless runs. 7 - Check the perfect inlet connection seal not to reduce the pump suction power. Fig. - Page 7 RIGHT WRONG A = foot valve B = check valve Fig. 6 15 - The horizontal sections of the suction pipe must be a bit inclinated towards to the top in order to avoid the creation of air pockets, which can damage the pump priming.

8 - If the duty speed is very high, it's normal that the bearing housing temperaturs reaches 50-60°C, expecially during the first working hours. 4. GENERAL MAINTENANCE 4.1 - LUBRICATION 1 - OMAC pumps are delivered ready filled with oil of ISO VG 68. Advised lubricants Tab. 9 Oil quantity Tab. 10 DUTY TEMPERATURE... - Page 10 1 - If the product is subjet to easy drying, crystallization or decantation, it's necessary to wash pump and piping system at the end of each work or at the beginning of a long plant pause. 2 - The reversibility of the rotation direction, peculiarity of all OMAC pumps, allows the product return, emptying discharge piping.

4 - Check the corrosion of the bearing housing; if necessary arrange its repainting by means of a paint, suitable to protect it from a quick wear. The OMAC standard pumps are painted with: BRIGHT EPOXID ENAMEL RAL 7032. If you carry out these checks sistematically, the pump will keep its initial performaces for many years. - Page 12 5.3 - MANUAL BY-PASS VALVE 1 - The relief valve can be used even as manual by-pass to adjust the capacity. 2 - Loosening the register screw (59), release the pressure on the spring so that to remove the piston (57) from the pumping chamber, letting part of the pumped liquid go back into the sucking chamber.
