Product Overview
When both elevated pressure delivery and larger pressure storage are required, the Lowara 3HM05P-PT18 delivers on both fronts. Combining the 52.5-metre pump platform with an 18-litre APT pressure vessel, this packaged system is ideal for residential and light commercial installations with multiple outlets, elevated distribution points, or where reduced pump cycling is desirable.
The AISI 304 stainless steel pump body and Noryl™ impellers deliver a maximum head of approximately 52.5 metres and a maximum flow rate of 70 litres per minute. The 0.75 kW motor operates on 220-240 V single-phase, drawing 4.56 Amps. Connections are Rp 25 mm threaded. The pump handles clean liquids at temperatures up to 60°C.
The 18-litre pressure vessel provides additional storage capacity, helping to reduce pump starts during periods of low demand. The mechanical seal is ceramic, carbon, and EPDM. The motor is rated IP55 with Class F insulation. Thermal protection is provided by an automatic reset overload device. The close-coupled configuration is suitable for floor mounting.
The unit is supplied with a pre-wired terminal junction box. The pump is certified for drinking water use under WRAS and ACS. Installation requires a level, frost-protected surface with adequate ventilation. The system is intended for clean water applications and should be installed with adequate clearance for maintenance access.

Where should this packaged booster be installed and how does the integrated diaphragm tank limit motor cycling?
Level floor mounting in a sheltered space is recommended for the 3HM05P-PT18, which integrates an 18-litre APT pressure vessel to buffer line demand and protect against excessive motor cycling.
What maximum dynamic head does this multistage pressure pump produce under service?
Operating across residential irrigation and boosting systems, the 3HM05P-PT-18 produces a maximum dynamic head of approximately 52.5 m.
What connection dimensions fit the inlet and delivery ports and what peak volume is pumped?
Plumbing integration is completed using Rp 25 mm (1") discharge and Rp 25 mm (1") suction, allowing the 3HM 05P PT18 to pump a peak flow volume of approximately 70 L/Min.
How is this multistage water booster protected against corrosion during domestic water supply?
Potable water distribution safety is delivered by the 3HM_05P_PT18 through AISI 304 stainless steel pump casing, Technopolymer impellers, and ceramic, carbon, and EPDM mechanical seal, satisfying WRAS and ACS drinking water standards for fluids up to 60°C.
Which electrical voltage and motor kilowatt power are needed to run this pressure unit?
Supplying electricity to the 3HM05P-PT18 requires a 0.75 kW motor connection on 220–240 V, 50 Hz, single-phase pulling 4.56 A, engineered with IP55 ingress protection.
