Franklin Pressure Pump 9AMH3B-51, 150 LPM - Single Phase, Includes 8L Pressure Tank and Pressure Switch

Franklin 9AMH pressure pump packages supply clean water for household use, garden irrigation and water distribution. Choose a pump model for the required flow and pressure, then select an 8L, 18L, 35L or 60L tank. Each package includes a fixed-speed multistage pump, pressure switch and the selected tank.

9AMH2B-51: 166.7LPM at 15.6m head; maximum head 23.7m.
9AMH3B-51: 166.7LPM at 22.8m head; maximum head 35.3m.
9AMH4B-51: 166.7LPM at 31.7m head; maximum head 47.4m.

These paired reference points show flow at a stated head. Maximum head is the zero-flow figure and occurs separately. Select the pump for the flow needed at the working head, allowing for pipe losses and height differences.

Pump inlet: 1 1/2" BSP female thread.
Pump outlet: 1 1/4" BSP female thread.

The pump determines the available flow and pressure. Changing tank size does not increase the pump’s performance. A larger tank generally stores more usable water between pump starts, helping reduce how often the pump starts during intermittent use.

Tank choices: 8L, 18L, 35L or 60L nominal capacity. These are vessel sizes, not the amounts of water available between starts; usable storage depends on the switch settings and tank precharge.

The pressure switch starts the pump when pressure falls to its start setting and stops it at its stop setting. Pressure varies between these settings during use. An installer sets the switch and tank precharge to suit the pump, required water supply and component pressure limits.

Use clean water without sand, solids or fibres. The pump body, impellers and diffusers use 300-series stainless steel.

The pump is not self-priming. Fill the pump and suction pipe with clean water before starting, and use a suitable valve arrangement to retain that water where suction lift is required. Install on a firm base with drainage and motor ventilation, following the pump manual.

Supplied for a 220–240V single-phase, 50Hz supply with an AU/NZ plug. Do not let the pump run without water; arrange suitable protection against loss of supply.

✓ Supplied Package & Control
Multistage pump, pressure switch and selected pressure tank included.
Tank choices: 8L, 18L, 35L or 60L nominal capacity; usable storage depends on pressure settings and precharge.
Fixed-speed operation; water pressure varies between the switch start and stop settings.
An installer sets the start/stop pressures within the pump's capability and every component's pressure rating.
A larger tank does not increase the pump's available flow or head.

✓ Pressure Limits
Maximum pump operating pressure: 1000kPa; inlet pressure plus pump pressure must remain within this limit. Other package components may have lower limits.

✓ Water Supply
Clean water without abrasive particles, solids or fibres.

✓ Installation & Priming
Not self-priming; fill pump and suction pipe before starting.
Use suitable inlet valves to retain prime where suction lift is required; follow the pump manual.
Install horizontally on a firm base with supported pipework, drainage and motor ventilation.
Arrange suitable protection against loss of water supply.

✓ Construction
300-series stainless-steel hydraulic components.

✓ Electrical Supply
Supply: 220–240V single phase, 50Hz, with AU/NZ plug.
