Product Overview
The Lowara 3HM03S-PT18 offers the durability of stainless steel hydraulics with the added benefit of an 18-litre APT pressure vessel. This packaged system is ideal for residential and light commercial applications where corrosion resistance is required and larger pressure storage is beneficial for reducing pump cycling in variable-demand systems.
The AISI 304 stainless steel pump body and impellers deliver a maximum head of approximately 21.9 metres and a maximum flow rate of 73.3 litres per minute. The 0.5 kW motor operates on 220-240 V single-phase, drawing 2.48 Amps. Connections are Rp 25 mm threaded. The pump handles clean liquids up to 60°C.
The 18-litre pressure vessel provides additional water storage, reducing pump starts during low-demand operation. 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 horizontal close-coupled configuration is intended for floor mounting.
Installation requires a level, frost-protected surface with adequate ventilation. The pre-wired terminal junction box simplifies electrical connection. The pump is certified for drinking water use under WRAS and ACS. The stainless steel hydraulic components and larger pressure vessel make this variant suited to systems with higher demand variability.

Why does the Lowara 3HM03S-PT18 come with an 18-litre pressure tank?
The 18L tank keeps water pressurized so the pump doesn't have to kick on every time you turn on a tap to rinse your hands. It stops the motor from constantly clicking on and off, which cuts down your power bill and keeps the pump running smoothly for years.
Is the Lowara 3HM03S-PT18 strong enough for a multi-story home?
Yes, it's ideal for multi-story houses. It pushes water up easily to top-floor bathrooms and showers while keeping pressure steady when several taps are turned on at once.
Does the Lowara 3HM03S PT18 require a lot of ongoing maintenance?
Not at all. It's designed for hassle-free daily operation with long-life sealed bearings and heavy-duty mechanical shaft seals. Just keep your water inlet strainer clear and it'll run reliably for years.
What materials is the Lowara 3HM03S_PT18 made from and can it handle warm water?
It's built with a 304 stainless steel body and stainless steel impellers, so it won't rust or corrode over time. It easily handles clean water at temperatures up to 60°C.
