Click the link to download the Quick Start Guide, or a more detail manual and sizing guide can be found here. We can help with sizing or any aspect of your pumping system project. The best way to start this conversation is to use the contact /help form and send us your well depth, static water level (SWL), Well's flow rate, Flow rate you would like to have from the well, Pressure you would like to have from the new pumping system, Distance from the well to the house or place of service, Change in elevation from the house to the service, Type and size of piping you which to use. This will be a great start to sizing you a new pump.

4" Multi-Impeller Borehole Pumps

These pumps are designed for clean water applications such as water boosting, gardening, irrigation, and lifting water from boreholes in residential, commercial, and agricultural systems. They must be installed in wells with a diameter of at least 4 inches, or in tanks or cisterns. They increase water pressure for uses like watering medium or large gardens or, in higher-capacity models, agricultural irrigation systems.

Construction Features of the Pump

Technopolymer impellers with stainless steel adjustment rings. Stainless steel components include the pump liner, shaft, motor coupling, integrated suction filter, and cable guard. Suction and delivery supports are made from micro-cast AISI 304 stainless steel. Includes a removable non-return valve made of technopolymer or stainless steel plate, depending on the model. Impellers are designed for high efficiency in accordance with PEI Directive (from 25 GPM). NSF61 certification is pending.

Construction Features of the Motor

Compatible with 4-inch motors: 4GG, 4TW, and 4GX.

- 4GG: Single and three-phase motors from 0.5 HP to 10 HP
- 4TW: Single-phase, 2-wire motors from 0.5 HP to 1.5 HP
- 4GX: Made entirely of SS316 stainless steel

4GG and 4GX single-phase motors require a control box (4CBUS line). 4TW motors operate without a control box and include an internal capacitor and thermal protector. All motors are CSA approved. NSF61 certification is pending. Suitable for use with Variable Speed Drive (30–60 Hz).
