Keco’s self-priming diaphragm pumps are based on a time-tested design that has been on the market for over 40-years. Keco’s Diaphragm pumps are designed specifically for pumping sewage | Sewage pump out systems | and require infrequent maintenance. All exposed surfaces are triple coated using zinc, epoxy and urethane, and are assembled using 300-grade stainless steel hardware. Encapsulated full-opening swing check valves protect from corrosion and ensure a consistent and reliable seal for many years. These rugged Diaphragm Pumps are affordable to operate and built for the Harsh marine environment. Keco developed a pump that would stand up to a wide variety of liquids, and be able to handle the most severe conditions imaginable. Although initially targeting marine pump out applications, Keco’s diaphragm pumps have proven effective as a multi-purpose pump. Keco diaphragm pumps are capable of pumping everything from Mud to Concrete slurry and can run dry without damage.

Diaphram Pump Technology:

Keco’s Diaphragm Pumps rely on the oldest and most traditional pumping technique. Mechanically similar to a plunger, the diaphragm pump bowl is filled when the diaphragm rises, and cleared when the diaphragm compresses. This reciprocating action causes the suction/discharge valves to fully open and close. An oversized inlet/outlet allow Keco’s Diaphragm pumps to pass 1.5" solids. This simple and effective pump has proven to be a reliable and a durable workhorse.


Maintenance Consideration:

Keco’s Diaphragm Pumps feature a modular design and are extremely intuitive to maintain. Consisting of mostly ½” stainless steel hardware these pumps can be disassembled with two wrenches. Rebuilding a Diaphragm Pump is as simple as replacing the Rubber Diaphragm and Flapper Valves, which can be done in less than an hour. Replacement parts are Affordable and Readily available.
