19 Foundation preparation (before pump installation)1. The area for anchoring the pump should be greater than the area of the pump base. If theanchoring area is too small, the base may be destroyed due to the concentrated load on it.2. If pump operation is to be subject to vibration (resonation with the piping, for example),provide an expansion joint between the pump and the piping. Otherwise, the piping, gauge, etc.,may be damaged.3. Installation advice• Use anchor bolts to fasten the pump base firmly.• Install the pump horizontally.• Sufficient space is required to allow cool air from the motor fan to circulate.• Allow ample space around the pump for easy and efficient maintenance work.8 PipingPPGBack Pressure ValveDischarge ValveAir Vent Valve(flushing valve)ExpansionjointExpansionjointDrain Valve(flushing valve)SuctionValvePressure ReliefSafety ValvePulsationDampener orAir Chamber Shut offValve Load of piping for LK-NWhen plumbing the pump, support the piping and use an expansion joint so as not to apply a loadonto the pump discharge/suction ports. General precautions1. All piping should be supported independently so that unnecessary weight and vibration are nottransmitted directly to the pump. Expansion joint is recommended to avoid damaging the pumphead especially.2. The best piping arrangement for minimum pressure loss is achieved with straight runs and fullbore piping containing as few bends and fittings as possible.
