The HydroForce™ Series 4 is an electronically-controlled, pressure-sensitive, submersible, centrifugal roto-dynamic pump with no reciprocating parts. Pressure-sensitive (demand) pump switches on and runs when there is a demand for water. Max head (nominal) 35 metres, pump pressure (nominal) at outlet 3.5 bar, max. suction 3 metres Dry-run Protection: when no water is detected for 8 seconds, the pump is turned off by the printed circuit board (PCB) in order to protect the motor and pump from burning out. Automatic reset after a period of 10 minutes. If water is still not detected, subsequent reset periods are 1.5 hours, 3 hours, 6 hours, 12 hours, 24 hours then back to the beginning of the cycle. Additionally, a thermal switch, not connected to the PCB, turns the pump off if motor overheats. It resets when cool which make take several hours. Alloy bulkhead, pressure release gap and twin chamber design prevents ingress of water to motor, electrical components and to bearing oil. Double bearing seal prevents egress of bearing oil. Alloy bulkhead dissipates motor heat to water in the second chamber. Logic processors in PCB prevent other pump anomalies and permit factory programming of reset timings. Inlet strainer and output pipe connector are factory-fitted and the seals tested to ensure proper running of the pump. Guaranteed for 2 years. Electricity consumption 800 watts at 220-240 Volts AC 50 Hz (requires 10 or 13 amp fuse and RCD mains socket). Connection cable 5m H07RN-F. Inlet port to the non-removable filter 1 inch (25mm) female BSP. Output port 1 inch (25mm) female BSP provided with push-fit connector for 1 inch (25mm) MDPE pipe (1 ¼ inch (32mm) connector option by special order). Dimensions L 565 W 185 H 260 mm, weight 13.1 kgs High-quality image-based instruction manual
