The Franklin 3AMH7B-51 is a single-phase horizontal multistage pump for clean-water transfer, pressure boosting, irrigation and washdown.
These listings are for bare pump-and-motor units. Suitable separate controls are required for automatic operation as taps open and close; a pressure tank is not included.
3AMH7B: 50LPM at 48.7m head; maximum head 75.3m.
The paired figures show flow at a stated head. Maximum head occurs at zero flow, separately from the listed flow. Allow for inlet conditions, height differences and pipe losses when selecting the pump.
Inlet: 1 1/4" BSP female thread.
Outlet: 1" BSP female thread.
The pump body, impellers and diffusers are 304 stainless steel. Use clean water without solid particles or fibres, compatible with the pump materials. Maximum water temperature is 55°C.
The pump is not self-priming. Fill the pump casing and suction pipe before starting, and use suitable inlet valves to retain prime where suction lift is required. Install on a firm base with drainage, supported pipework, ventilation and protection from weather and freezing. Do not run without water or against a closed outlet.
Maximum operating pressure is 1000kPa; inlet pressure and the pressure added by the pump must remain within this limit.
Single phase, 220–240V, 50Hz; AU/NZ plug. The motor has built-in thermal overload protection.
Two-year Franklin Electric pump warranty, subject to its terms.
