Aker Solutions’ new Wirth triplex double-acting piston diaphragm (TDPM) pump combines two well-established and proven pumping principles for the transport of high volumes of abrasive slurry. The Wirth TDPM provides flow rates of up to 1,400 m3/h at discharge pressures up to 8 MPa in the 3,000-kW input power version. This, the company said, is a significant increase in capacity compared with conventional piston diaphragm pumps. The Wirth TDPM 3000 can be used for traditional applications such as slurry pipeline transport, autoclave feeding, mine dewatering and ore hoisting. Additionally, the pump is claimed to be an efficient solution for pumping thickened oil sand tailings.
