Detail
1YESGate Valve, may also be fitted closer to the pump in case of long pipework
2N/AWith a positive suction head tilt the pipework towards the direction of the pump inlet
3YESIn-Line Strainer, required if there are particles present, larger than 6 mm
4NOAir Pockets, the circuit needs to be as short and as straight as possible
5YESPipe connectors
6N/ASuction line needs to be as short and direct as possible, ideally the same size as the pump inlet or 1 size larger.
7YESAttachment for Pressure Gauge or Pressure Relief Valve. It is best practice to install a Pressure Gauge on the discharge of the pump to evaluate where it is working on its curve. A Pressure Relief Valve is required when there is a possibility for “Dead Head” operation or when using a Nozzle for example.
8YESGate Valve, useful for regulating the performance of the pump.
9 Bends in in the pipework need to be ideally placed after any valves and instrumentation and ideally placed five times the ø of the pipework away. I.e. if the pipework is 25 mm then any bends would ideally need to be placed 125 mm away from the pump and any valves or instrumentation.
10YESAttachment for Pressure Gauge or Pressure Relief Valve. It is best practice to install a Pressure Gauge on the discharge of the pump to evaluate where it is working on its curve. A Pressure Relief Valve is required when there is a possibility for “Dead Head” operation or when using a Nozzle for example.
11NOElbow Joints & other bends on the pump suction or discharge ports
12N/AWhen operating the pump in a suction lift application ensure that the suction pipework is as short as possible and contains as few bends as possible. Also ensure that a Non Return or Check Valve is installed at the pump inlet or at the bottom of the suction pipe.
13YESCheck Valve / Non Return Valve, essential when operating a suction lift application.
14YESSuction Strainer, essential when there is the potential for solids in suspension larger than the capability of the pump.
15N/A 
16N/ASuction Head, the distance between the pump inlet and the surface of the fluid. This needs to be no more than the capability of the pump in question.
17N/AImmersion Depth, the distance between the surface of the fluid and the bottom of the suction pipe.
18YESExpansion Joint, indispensable with long pipework and / or hot liquids Anti-Vibration Facility, considered best practice when using the pump on a fixed & rigid pipework.
19YESOvercome obstacles on both the suction and discharge by lowering the pipework where possible. Essential on the suction side, ideal on the discharge side. This reduces the work the pump has to overcome as well as eliminating the possibility of air pockets.
20N/AFix the pump into the installation by the fixing holes provided, the supports and / or base must be level.
21YESDrainage Channel, it is best practice to allow for a drainage channel around the base of the pump to allow for easy drainage of the pump without contaminating the installation. Pumps can be supplied with drainage valves / ports and / or drainage facilities on their base frames or trolleys.
