Orange Pumps CJ750-SW66 Cast Iron Shallow Well Pressure Pump for Pressurised Water Supply with 35 Litre Tank

Drawing water from underground wells or surface sources to overcome steep elevations is the intended application for this three-phase pressure system. It is specifically engineered for rural sites requiring an automated high-head supply for irrigation lines and pressurised troughs. The inclusion of a pressure tank reduces pump cycling while providing automatic water supply.

This model features a 1.5 kW motor operating on a 415v three-phase supply with a rated current of 3.5 Amps per phase. Hydraulic performance is characterized by a maximum head of approximately 69 m and a maximum flow rate of 67 L/Min. This configuration is optimized for high-static head installations where vertical lift is the primary hydraulic requirement.

Factory-fitted with the WK-CJ30-50 water kit and a Type D mechanical switch, the system includes a 35 litre pressure tank for automatic operation. Its internal high-head SW66 injector works with the jet and venturi design to maximize pressure while effectively purging air from the casing. The 35 litre tank provides 10.8 litres of draw-off, which significantly reduces motor starts during frequent daily site duties.

The construction includes a solid cast iron body and a double race bearing system designed for mechanical strength and longevity. The Type D mechanical switch contains no sensitive electronics, making it well-suited for areas prone to brownouts or lightning strikes. The unit features TEFC protection, a 2-year warranty, and is rated for liquid temperatures reaching a maximum of 65°C.

FEATURES

• Heavy-duty cast iron body provides a rigid housing capable of withstanding the rigors of demanding agricultural and farm service.
• WK-CJ30-50 water kit includes a stainless steel barrel union, gate valve, and pressure gauge for site monitoring.
• Integrated 35 litre pressure tank provides approximately 10.8 litres of draw-off to reduce energy consumption and motor start cycles.
• Type D mechanical switch offers superior resistance to voltage spikes and power fluctuations in remote property sites.
• SW66 injector configuration is designed to achieve high discharge pressures for high-head agricultural tasks.
• Double race bearing arrangement manages axial forces and radial turbulence to extend the service life of the motor.
• Corrosion-resistant stainless steel shaft and TEFC protection help protect the internal assembly from moisture and local vermin.
• Large oval casing holds ample water around the impeller to assist with self-priming.
