The HydroForce Series 3 is an electronically-controlled, pressure-sensitive, submersible, centrifugal roto-dynamic pump with no reciprocating parts. Pressure-sensitive (demand) pump which turns itself off until 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 30 minutes. If water is still not detected, subsequent reset periods are 1.5 hours, 3 hours, 7 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 when motor overheats. It resets when cool which make take several hours.
| NEW: Alloy bulkhead (pictured below), pressure release gap and twin chamber design prevents ingress of water to motor, electrical components and to bearing oil. NEW: Double bearing seal prevents egress of bearing oil. NEW: Alloy bulkhead dissipates motor heat to water in the second chamber. NEW: Logic processors in PCB prevent other pump anomalies and permit factory programming of reset timings. NEW: Inlet cartridge filter, 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 10m 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 (11/4 inch (32mm) connector option by special order). Dimensions L 565 W 185 H 260 mm, weight 13.1 kgs.
