Jecod 'Professional' Range DCP PumpsThese new pumps improve on the previous DCP pump design as follows:Sine Wave controller technology provides super quiet operationNew Digital Controller- Speed Control Settings Between 30%-100% in 1 Watt increments (DCP-4000 and DC-P2500 has an 8 speed controller) Digital display of power consumption. Suitable for external and internal operation Seals for input and output connections Improved Head Pressure Performance over DCP Models New Enclosed Impeller Design For a more Quiet Operation Energy Saving up to 65% IC Electronic Detection- Automatic Power Off Protection Upon No Water Wear Resistant Ceramic Shaft DCP-13000 (95W)This unit has a maximum flow rate of up to 13,000 litres/hour - adjustable from 5,000 - 13,000 litres per hour (in 8 steps). Electronic detection of no water enables automatic power off protection Motor protection if rotor is blocked Can be used in Marine and Freshwater applications No copper elements Long operation life is achieved by the use of wear resistant ceramic shaft Soft start operation - pump gradually builds up to set flow rate Feed mode disables pump for 10 minutes Speed settings (30% - 100%) in 1Watt (or 8 steps for DCP-2500/4000) steps with power consumption indication - setting is retained if power is lost.
