Premium Water Pump Kit

Our top performing pump kit, for households wanting stronger pressure and the reassurance of a premium pump. The Promax Premium Water Pump Kit is built around the Grundfos JP 4-47 jet pump with the PM1 pressure manager, and suits larger homes or those with multiple bathrooms and higher water demand.

The PM1 holds constant pressure, so the shower does not drop away when someone flushes the toilet or the washing machine kicks in, and its built-in dry-run protection matters if you are relying solely on tank water. Every kit includes a discreet Promax pump cover and all the fittings needed for a fast set up.

The pump

• Maximum flow 67 litres per minute
• Maximum head 44.5 metres
• Single phase 230 V, plug and play
• Stainless steel AISI 304 pump housing with a composite PPO-20GF impeller
• Grundfos PM1 pressure manager pre-fitted, with dry-run protection
• Performance certified to ISO 9906:2012 grade 3B, so the published curve is what you actually get
• Built on the Grundfos global platform, with a proper spare parts and service network behind it

What it suits

Larger homes, two bathrooms, or a house sitting well above the tank. For a standard three-bedroom home the Economy Water Pump Kit will usually do the job for less.
