Marine-rated, per manufacturer datasheetCapacity
Condensate/hot waterMedium

Side-channel pumps like the SIHI LPH are commonly found in marine boilers and condensate systems, where they handle condensate and hot water. Designed for marine environments, these pumps are essential for maintaining efficient boiler operations. They feature an electric drive mechanism and are specifically tailored for use in boiler and condensate services. Common issues that can arise with these pumps include mechanical seal leakage, stage wear due to cavitation, bearing wear, and reduced capacity due to internal clearance wear. To ensure the pump operates at peak efficiency, regular maintenance and inspection are crucial. It is important to monitor suction conditions and pressure, and to address any seal leakage promptly. During scheduled overhauls, inspecting the stages is also recommended. Spare parts such as mechanical seals, bearings, stage components, O-rings, and gaskets are readily available to facilitate quick repairs and maintenance.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
