Orange Pumps CJ750-SW38 Cast Iron Shallow Well Pressure Pump for Tank Filling with 18 Litre Tank

Rapid tank filling and high-volume automatic water transfer are the primary service duties for this pressure pump. It is designed for rural property management where clean water from rivers or dams must be automatically moved to storage systems or high-demand troughs. The integration of a pressure tank transforms the base jet unit into an automatic solution for pressurised site distribution.

Operating on a 240v single-phase power supply, the 1.5 kW motor draws a rated current of 9.7 Amps. Hydraulic performance reaches a maximum flow rate of up to 172 L/Min and delivers a maximum head of up to 45 m. This performance profile establishes the system as a high-volume solution for moving substantial volumes over moderate elevations.

This model is supplied with the WK-CJ30-50 water kit, which includes the Type D mechanical switch, pressure gauge, gate valve, and an 18 litre pressure tank. The SW38 injector works with the jet and venturi design to maximise water volume while purging air from the casing for reliable self-priming. The pressure tank provides approximately 5.6 litres of water draw-off between pump starts, helping reduce pump cycling and maintaining water availability for small demand.

Construction features a solid cast iron body and a double race bearing system that helps the motor handle axial forces from the impeller and radial forces caused by water turbulence. The unit includes a stainless steel shaft, TEFC protection against dust and moisture, and a carbon ceramic shaft seal for reliable operation. The hydraulically tuned pump and integrated pump design generate maximum water flow and pressure while maintaining a low motor load.
