Product Overview
For installations where larger pressure storage delivers tangible benefits, the Lowara 3HM04P-PT18 combines the proven 3HM04P hydraulic platform with an 18-litre APT pressure vessel. The increased vessel capacity makes this variant particularly well-suited to multi-outlet residential systems and commercial applications where reduced pump cycling is a priority.
The AISI 304 stainless steel pump body and Noryl™ impellers deliver a maximum head of approximately 40.3 metres and a maximum flow rate of 70 litres per minute. The motor is rated at 0.5 kW, operating on 220-240 V single-phase, with a current draw of 3.34 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 water storage, helping to reduce pump starts during low-demand periods. The mechanical seal is ceramic, carbon, and EPDM. The motor is rated IP55 with Class F insulation. Thermal overload protection with automatic reset is included. The horizontal close-coupled design allows installation in equipment rooms with limited floor area.
Installation is straightforward with the pre-wired terminal junction box. The pump is certified for drinking water use under WRAS and ACS. The unit is intended for clean water applications and requires a frost-protected, well-ventilated installation location. The larger pressure vessel makes this variant suitable for systems with higher demand variability.

Why does this booster system incorporate a diaphragm accumulator tank and how should it be mounted?
Hydraulic volume dampening is delivered by an integrated 18-litre APT pressure vessel on the 3HM04P-PT-18, keeping water stored and supporting indoor floor mounting.
How much elevation pressure can this surface booster pump generate during operation?
Maintaining dependable plumbing pressure, the 3HM 04P PT18 provides a peak dynamic head rating of approximately 40.3 m under standard test ratings.
Which plumbing thread connects to the pump connections and what maximum flow rate is provided?
Connecting to household pipework requires Rp 25 mm (1") discharge and Rp 25 mm (1") suction, with the 3HM_04P_PT18 generating a maximum discharge of approximately 70 L/Min.
What materials protect the fluid pathways of this booster pump against internal corrosion?
