Product Overview
Residential and light commercial pressure boosting with the durability of stainless steel is delivered by the Lowara 3HM05S-PT8. This packaged system combines a 35.2-metre pump with stainless steel hydraulics and an 8-litre APT pressure vessel, providing consistent performance and corrosion resistance in clean water service.
The AISI 304 stainless steel pump body and impellers deliver a maximum head of approximately 35.2 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 2.85 Amps. Connections are Rp 25 mm threaded. The pump handles clean liquids up to 60°C.
The 8-litre pressure vessel reduces pump cycling during low-demand periods. The mechanical seal is ceramic, carbon, and EPDM. The motor enclosure is IP55 with Class F insulation. Thermal protection is provided by an automatic reset overload device. The horizontal close-coupled configuration is designed 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 provide increased corrosion resistance in clean-water applications.

Is the Lowara 3HM05S/PT8 motor safe to install outside in the weather?
Yes, it is. The 0.5 kW motor has an IP55 weatherproof casing, so it handles rain, dust, and outdoor conditions with no trouble. It plugs into standard home power and includes built-in thermal overload protection.
Does the Lowara 3HM05S PT8 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 does the 8-litre pressure tank do for the Lowara 3HM05S-PT8?
The 8L tank acts as a handy water buffer. When you turn on a tap just a little bit, water comes straight from the tank first. This stops the pump from starting up unnecessarily, saving power and protecting the motor from wear.
Is the Lowara 3HM05S-PT8 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.
