Arranging Your Pump Correctly Despite the simplicity of plug and play pumps, there are a few important precautions that one must consider in order to optimise the effectiveness of the pumping application. Arrange the pump so that it doesn’t burrow itself into sand or clay. The burrowing of a submersible pump is a common problem that occurs on construction sites. Burrowing can be avoided by placing the pump on a bed of coarse gravel or on a wooden plank. The pump can also be hung freely by a rope or chain, or put into a cut-down and perforated oil drum. Alternatively, a pontoon or floatation device can be used. Avoid sharp bends on the hose Any sharp bends, kinks or pinching of the hose reduces the capacity of the pump. Avoiding any hose anomalies can dramatically increase the efficiency of the pumping application. Grindex submersible pumps have a rotatable discharge connection. This can be very helpful in preventing any bends or kinks. Tandem connections In order to achieve higher pumping heads, two or more drainage pumps can be connected in series. For this purpose, a series connecting flange is available as an accessory. When pumping
