Self-priming horizontal surface pumps for pumping clean water in household and gardening applications.

They are also used in a wide variety of applications with clean water or non-aggressive fluids in agriculture, in decanting and elevation between tanks, and in washing equipment, and as pressurising equipment for supplying farms, household irrigation, gardens and in homes.

With a compact and robust design, they are lightweight and easy to operate and maintain. The ejector unit and diffuser have an exclusive design that provides high suction capacity. They are available with 1" threaded suction and discharge.

The operation of DELTA can be automated by adding Kit 02 or Kit 05 equipment for controlling stopping and starting according to demand, keeping the water supply pressure constant.

For automation, they include thermal protection in the motor in single-phase models.
