Product Overview
The DAB 251PRO is a heavy-duty self-priming jet pressure pump designed for high-demand water transfer, irrigation, and pressure boosting applications. Engineered for installations where water must be lifted from tanks, rivers, or dams, it delivers strong suction performance even in the presence of air or light sandy particles.
This pump is suitable for domestic water supply, horticulture, and small-scale agricultural use, as well as washdown and light industrial services. Its twin impeller configuration enhances hydraulic efficiency and enables higher pressure output for systems requiring consistent and stable delivery.
Constructed with a GJL 200 cast iron pump body, the unit provides excellent structural strength and durability. The hydraulic components including the impeller, jet, venturi, and diffuser are manufactured from glass reinforced Noryl, ensuring efficient flow characteristics and resistance to wear. A carbon ceramic nitrile mechanical seal and nitrile O-rings provide reliable sealing performance.
This model delivers a maximum head of 62 metres and a maximum flow rate of 120 L/Min. The integrated jet and venturi system supports a suction capability of up to 8 metres under optimal conditions, ensuring dependable self-priming operation.
Powered by a 1.85 kW single-phase motor operating on 240V, the pump features a TEFC motor design with auto-reset thermal overload protection. Operating at 2800 RPM with an IP44 protection rating, it ensures safe and consistent performance. The nXt PRO dual mode controller enables automatic operation, includes a built-in check valve, and provides dry run protection to safeguard the system.
The pump supports a fluid temperature range from 0°C to 35°C and operates at a maximum pressure of 8 bar. It is approved for drinking water applications as per AS/NZ 4020 certification, making it suitable for potable water systems .
