The Umbra Pumps Acuabig Industrial well pumps series are multi stage pumps for use in a variety of applications where a large flow rate, at a high pressure, is required. They are suitable for pumping potable water and water containing up to 60 g/m³ of  suspended solids. They have 304 stainless steel bodies and strainers with Noryl diffusers and impellers. Pump stages are fitted with 304 stainless steel rings for enhanced wear resistance. The 420 stainless steel shafts are fitted with mechanical seals, intermediate oil chambers and inner lip seals, which offer excellent wear resistance. For simple and easy installation this series features integral motor protection and starting capacitors. All models are supplied with 20 metres of heavy duty rubber power cable. The series is available with or without a float switch, however the flow on the manual versions (no float switch) of the Acuabig 200s can alternatively be controlled by including a pressure control in the delivery line.
