Franklin MH20 horizontal multistage pumps supply clean water for pressure boosting, water transfer, irrigation and washdown.
Suitable applications include commercial, agricultural and industrial water distribution and compatible circulation systems.
Supplied as a bare pump-and-motor unit. Automatic start/stop operation requires a suitable separate controller; a pressure tank is not included.
20AMH2B-53: 333.3LPM at 23.1m head; maximum head 31.2m; 2.2kW motor.
20AMH3B-53: 333.3LPM at 34.6m head; maximum head 46.8m; 3kW motor.
20AMH4B-53: 333.3LPM at 46.3m head; maximum head 62.5m; 4kW motor.
20AMH5B-53: 333.3LPM at 58.9m head; maximum head 78.5m; 5.5kW motor.
The paired figures show flow and head together; they are reference points, not maximum-flow ratings or a nominated ideal duty. Maximum head occurs at zero flow. Allow for inlet conditions, height differences and pipe losses when selecting the pump.
Inlet: 2" BSP female thread.
Outlet: 1 1/2" BSP female thread.
The pump body, impellers and diffusers are 304 stainless steel, with reinforced tie-rod construction and a carbon/silicon-carbide mechanical seal with EPDM elastomer. Use clean water without solids or fibres, compatible with the pump materials. Maximum water temperature is 85°C for domestic and commercial use; the 110°C limit is for industrial applications only.
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.
The stocked versions use a 380–415V three-phase, 50Hz supply. Connection by an electrician and suitable external motor overload protection are required.
Two-year Franklin Electric pump warranty, subject to its terms.
