Planning Installation – Pump Location

Planning Installation – Pump Location

1. J Dry location

Installing a pump at a location with high humidity will cause the bearings to rust and/or motor insulation resistance to decrease, which can shorten the life of the motor.

2. Ambient temperature under 40°C

When ambient temperature is high, such phenomena as poor motor ventilation, increase in motor temperature, decrease in insulation resistance, etc.; can occur It is advisable, therefore to install the pump not only in a well-ventilated location but also as far as possible from a high temperature unit, such as a boiler.

3. Allow sufficient space for disassembly and inspection

A cramped location makes pump inspection and disassembly difficult, resulting in undue consumption of time. Too, even daily maintenance is apt to be neglected, which will, of course, affect the life of the pump. Be sure to allow enough space above as well as around the pump.

4. Indoor installation

Motors suitable for general-purpose pumps are usually designed for indoor use. If the motor is to be installed outdoors, however, it must be provided with a protective covering against rain. Such shelter must be well-ventilated and large enough to ac- commodate radiation of motor heat. When a motor is installed outdoors. without covering, insulation resistance will decrease or the pump may rust, either of which can lead to unexpected accidents. =

5. Vibration absorbing base and flexible joints

Use of a vibration absorbing base reduces vibration usually transmitted to the floor on which the pump and its ancillary equipment are installed. When selectina vibration absorbing base, it is recommended the matter be discussed first with a construction engineer. Make sure the supports are provided with rubber packing.
