DAB KPS and KPF: High-Pressure Peripheral Pumps

The compact solution for constant pressure and technical systems

The DAB KPS and KPF series are designed for all applications requiring high pressure with low flow rates. Thanks to their extremely compact size, they are ideal for integration into machinery, powering small boilers, or solving low water pressure problems in domestic settings.

  • ✅ Mini Size: Easy to install even in the tightest spaces (e.g. under the boiler).
  • ✅ Anti-Seizing: The KPS 30/16 and KPF 30/16 models include brass inserts to prevent the rotor from seizing after long periods of inactivity.
  • ✅ Robustness: Cast iron pump body and brass impeller for guaranteed durability over time.

Pressure where needed, minimal footprint

Unlike traditional centrifugal pumps that require large impellers to push water upward, the DAB KPS and KPF pumps use a vane impeller that forcefully "pulls" the water, generating high pressure even at low speeds. This makes them perfect for solar thermal systems, air conditioning systems, or small domestic pressure tanks.

🔍 What is the difference between KPS and KPF?

Both are peripheral pumps, but they differ in design:

  • DAB KPS: It has a more square and compact design. It's the quintessential "little one," perfect as an on-board component or for small water boosters.
  • DAB KPF: It has a pump body with a classic front flange. It is often used as a domestic booster pump or for small drip irrigation systems where constant pressure is required.

Pay attention to the cleanliness of the water

Due to their construction, the tolerances between the impeller and the pump body are minimal. This means that DAB KPS and KPF pumps do not tolerate sand or impurities. Installing a mesh filter on the suction side is always recommended to protect the pump and ensure its long-lasting operation.

Frequently Asked Questions about KPS and KPF

Are they self-priming pumps?

No. The KPS and KPF series are peripheral centrifugal pumps. They only function properly if the water reaches the pump "gravity" or if the suction pipe is already filled and equipped with a foot valve.

The pump hums but doesn't spin, what's going on?

It's most likely blocked by limescale or a small impurity. Thanks to the slot on the back of the motor, you can try to unblock it manually with a screwdriver by turning the shaft before turning it on.

Which of the two is quieter?

Both produce a slight, high-frequency hissing sound typical of peripheral pumps. To reduce noise, be sure to mount them on anti-vibration mounts or avoid overtightening the rigid pipes.
