FORWATER PYPZ-K680 Permanent Magnet Booster Pump

The PYPZ-K680 sits in the middle of the PYPZ-K/R series permanent magnet booster pumps, where many residential projects land: 0.68 kW (0.9 HP), a 43 m maximum head and up to 75 L/min of flow at 4,000 r/min. It is the usual answer for two- and three-storey homes that need real pressure at a top-floor shower while the kitchen and garden tap are in use.

Key Features

• Frequency-conversion constant pressure, one-click pressure adjustment — speed tracks demand and the working pressure is set on the controller
• Voltage regulation and protection — stable running under supply fluctuation
• Pressure, flow and temperature detection — the controller reads system conditions continuously
• Permanent magnet motor — high efficiency, stable and energy-saving
• Noiseless operation — quiet enough for installation inside the home
• Compact design, easy installation — 25 mm ports, 8 m suction head, 6.6 kg gross weight
• Intelligent control — automatic start/stop with integrated protection

Applications

• Extracting water from wells within the 8 m suction limit
• Hot water pressurization, booster-up / booster-down and timed tank filling

Why Choose FORWATER

Choosing the PYPZ-K680 is usually about balance: enough head to reach an upper-floor shower and enough flow for several outlets at once, without paying for a larger pump than the building needs. The 43 m shut-off head and 75 L/min maximum flow cover the common mid-size residential duty point, while the permanent magnet drive keeps energy use proportional to demand.

FAQ

Will it hold pressure when the garden tap is open too?

The controller raises motor speed as demand grows, so outlet pressure stays at the set value across a wide range of simultaneous use. For larger properties the PYPZ-K880 offers more head and flow.

Do I need a pressure tank with this pump?

No large pressure vessel is needed for normal household supply because pressure is regulated electronically. A small expansion vessel still helps where the system has frequent small draw-offs.

Is it suitable for hot water lines?

It handles liquids from 4 °C to 50 °C, which covers typical domestic hot water pressurization. For higher temperatures, speak to our team before specifying.
