The Manifold Primer, aka Water Trap, (MP) is a device positioned between a water pump being primed and a source of vacuum pulling the water. It is designed to stop water flow when water reaches it. The Protek Specialty Manifold Primers are used with water pumps, in liquid propane gas engines, and for gasoline powered engine manifold priming. Our high quality pumps are made in the USA, and ship globally. Choose from the MP1000, MP2000, or request a custom manifold primer order consultation.
Manifold Primer Uses
LP or Gasoline Engine Intake. Manifold primers like our proprietary MP1000 are used to initiate suction when the vacuum source is the intake manifold of a multiple-cylinder gasoline or LP gas engine, or brake booster of a vehicle.
Water Pump Trap for Vacuum Pumps. As a water trap it is used when the vacuum source is a vacuum pump. The manifold primer/water trap utilizes a mechanical float valve that stops airflow as water enters the unit, thus “trapping” and preventing the water from continuing past it.
Other Manifold Primer Names: Although the primary name for this type of suction device is manifold primer, there are other nicknames and synonyms to describe them in different industries including: manifold primer water pump, vaccum manifold primer, manifold vacuum primer, irrigation manifold pump, water manifold pump.
Difference Between MP1000 and MP2000
- MP1000 – Has 3/8 NPT flow ports, IN at bottom and OUT at top. Mounting requires four 1/4″ bolts or screws. Water drains from the unit through the priming line.
- MP2000 – Has 1/2 NPT IN and OUT flow ports on the bottom. Mounting requires two 1/4″ bolts or screws. Water drains from the unit through an umbrella valve on the bottom of the primer.
