You can depend on Hydromatic self-primer pumps to provide years of reliable service. Thousands of units are operating trouble-free throughout the world.

Hydromatic self-primers are designed for economical long-term operation. You'll find a number of unique features to make service and maintenance quick and easy. Quick and easy service means you'll reduce downtime and save money.

You mount the Hydromatic self-primer on top of the wet well or sump and drop the piping into the hole. Fill the case with water, connect piping, power up and you're running.

When you turn the pump on, it automatically "self-primes." The flap check valve retains the prime in the pump and suction leg to give you worry-free operation.

External adjustment allows you to easily maintain original operating efficiency and peak performance. By simply turning the external cap screws you easily adjust the clearance between the impeller and wear plate.

You can make the external adjustment without disturbing the system. You don’t have to disassemble the pump and pipes.

Dependable Operation

You get dependable pumping operation with the Hydromatic Dual Seal System. Two seals protect the bearings to give you longer pump life.

We are aware of no other manufacturer that offers you this type of seal design for long-term, reliable pump service.

The unique dual seal system incorporates an oil chamber which provides lubrication for the seals.

The inboard seal offers protection because it "self-seals" tightly against the stationary face with pressure surges from the volute.

Hydromatic pumps use low friction, long-lasting John Crane® Type 21 mechanical seals that you can obtain off-the-shelf worldwide. Tungsten Carbide seals are optional.

The Hydromatic Dual Seal System offers you long, dependable pump operation.

Easy to Service

The Hydromatic self-primers are easy to service with their unique check valve design. Two "knock-off" tee handles allow quick and easy cleaning or replacement of the Suction Flap Valve.

Easy cleaning means you save energy and money. With Hydromatic self-primers you can replace the Suction Flap Valve without disturbing the piping.

Some other manufacturers require you to drain the case, disconnect the suction pipe, disconnect the suction elbow, and then replace the check valve. Everything has to be put back together and the case refilled to resume operation.

With the 3", 4", and 6" Hydromatic pumps, you unscrew the handles, lift the cover, or Priming Cap, replace the flapper, and start up the pump. All in minutes.

You don’t have the mess from draining the case and you don’t have to refill the case when done. Hydromatic self-primcrs are easy to service, no-hassle, with their unique check valve design.

Maintenance is simplified on the Hydromatic self-primer with (1) easy removal of the suction elbow and (2) easy back pull-out of the impeller and shaft, without disconnecting the piping.

You can quickly unscrew four "knock-off' tee handles on the suction end to remove the suction elbow. It's easy to clean or inspect the impeller without disturbing the piping.

The back pull-out design allows you to quickly inspect or service all wearing and rotating parts without disconnecting any pipes. You easily and quickly maintain the shaft, bearings, seals, impeller and wear plate with less downtime and less work.

Hydromatic self-primers are available with V-belt drive in order to save space and money. When space is expensive or just not available, the V-belt configuration allows the motor to be mounted piggyback above the pump, or to the side of the pump.

The Hydromatic direct drive option with flexible coupling reduces shaft stress so you get longer pump life. It is easier to maintain and keep running for years.

For special limited applications, you can get the Hydromatic self-primer in stainless steel for virtually corrosion-proof operation.

Corrosion resistant stainless steel pumps provide you with years of reliable service under demanding conditions.
