H2Ocean P4 PRO Dosing Pump

These smart pumps have been jointly developed between D-D and Kamoer, a company with a strong reputation for the manufacture of medical grade dosing equipment, ensuring a high quality product with excellent reliability.

The footprint of these new pumps is incredibly small as the body of both versions are under 250mm wide and only 50mm deep.

The 'P4 PRO' version of our dosing pump utilises direct drive geared DC motors for the ultimate in dosing accuracy and precision at an affordable price.

The pumps will provide simple, flexible and precise control of supplement additions to your aquarium through the easy to use Kamoer remote App  (Android and IOS).

Aggressive Chemicals: The pump heads and hose fitted to our pumps as standard are suitable for handling certain more aggressive chemicals that are commonly used in the aquarium, such as Iodine and Reef Zlements pH Plus. This is not always the case for other manufacturers.
