The Acuasub series are multi-stage pumps for high pressure, high head pumping in agricultural and industrial applications. They are lubricated and cooled by non-toxic oil. Suitable for pumping potable water and water containing up to 60 g/m³ of suspended solids. Supplied with an external, inline starter and thermal protection box. Flow can be controlled by including a pressure switch in the delivery line (see here).
A stainless steel sand filter, with a mesh size of 80 microns, is available as an optional extra to prevent damage to the pump from abrasive solids.
