Product Overview
Large-scale water supply networks requiring reliable extraction from deep 4-inch boreholes are the domain of this submersible pump, serving municipal and industrial fluid transfer duties where consistent high-volume delivery is essential. The floating impeller configuration maintains stable hydraulic performance in groundwater containing suspended particulates.
Driven by a 415V three-phase motor rated at 3 kW, the unit draws 7.1 Amps during normal operation. Maximum flow reaches 90 L/Min while maximum head extends to 204 metres. The hydraulic performance characteristics support deep well installations where significant vertical lift is required.
Floating stack construction permits the pump to handle liquids containing up to 150 g/m³ of suspended sand without mechanical binding. The front wear ring works in conjunction with the floating impeller to improve abrasion resistance, while the hexagonal shaft provides effective impeller drive. An integrated non-return valve is positioned at the outlet to block descending water columns when the motor deactivates.
Manufactured with a 304 Stainless Steel external casing and technopolymer diffusers and impellers. The discharge head and motor adapter are precision-cast stainless steel, offering corrosion resistance for prolonged submersion. This complete three-phase model includes a heavy-duty heatshrink kit for waterproof deep-water splices, with the pump designed for continuous operation in liquid temperatures up to 35°C.

How high can this high-capacity borehole pump push water?
Delivering substantial vertical lift from deep 4-inch boreholes, the 4GS30T reaches a maximum head of 204 metres at 90 L/Min.
What is the maximum liquid temperature this deep-well pump can handle?
The 4GS-30T is designed for continuous submerged operation in fluid temperatures up to 35°C.
How does the internal hydraulic stack prevent wear from abrasive sand?
Floating impellers and front wear rings in the 4GS 30T allow sand concentrations up to 150 g/m3 to pass without binding.
Does this submersible pump prevent water column reversal on shutdown?
An integrated stainless steel non-return valve in the 4GS_30T stops water column backflow and prevents reverse rotation.
What electrical supply and current draw are required for this 3 kW motor?
Running on a 415 V three-phase supply, the 3 kW motor of the 4GS30T draws 7.1 Amps during operation.
