Product Information :

The Jabsco 22130-2721 is a self-priming macerator pump with a Neoprene Impeller, Lip Type seal, coupled to a 1/4 Horsepower, 2850 RPM, 110/220 Volts AC, 1 Phase, 50HZ Motor. This macerator pump has Stainless Steel wearplates, with a Stainless Steel Cutter Plate with a new 4 blade design that reduces the particle size to 1/8 Inch (3mm) maximum. The Jabsco 22130 series AC macerator pump unit is the ideal solution for emptying marine holding tanks when not in a discharge restricted area. This pump will empty a typical 30 gallon (115 litre) holding tank in less than 3 minutes. It is recommended that holding tanks be flushed with several gallons of water after each pump out. This will reduce the possibility of a continued build up of sediment in the tank which could cause a potential blockage. This unit depends on liquid pumped for lubrication. Do Not Run Dry for more than 30 seconds. Lack of liquid will damage the impeller and the pump components. This pump has a nominal flow rate of 12.2 GPM, and is self-priming from dry up to a 4 foot lift and may be located at any convenient point in the waste discharge system. Be sure suction lines are airtight or pump will not self-prime.

This Jabsco macerator pump unit Capable of passing waste, toilet tissue, facial tissue, cigarettes, cigars, chunks of soft fruit or vegetables less than 1 Inch size, fish scales, or bait residue. It is Not designed to pass fruit pips, rags, wet strength kitchen towels, tampons or sanitary napkins. Installation The pump can be mounted in any position; however, if mounting to a vertical surface, the pump head should be affixed below the motor to avoid any water dripping onto the motor. The Macerator pump can be screwed directly into a 11/2 Inch NPT tank flange or female pipe fitting. If attaching the inlet port to a pipe fitting it may require removal of the hose barbed port, this can be done using a hacksaw. Wrap port threads with a couple of wraps of Teflon tape and screw the pump assembly into the pipe fitting. Tighten hand tight, do not over tighten. An air leak anywhere in the suction side of the plumbing system can cause extended dry running. All suction connections must be air tight and free of sharp bends or restrictions. If a deck fitting is installed for dockside pumpout and connected to the suction hose of the macerator by means of a tee fitting, it too must be air tight to ensure proper priming. Use minimum 1 Inch ID hose for discharge and connect to thruhull fitting located approximately 46 inches above waterline. Consult with a qualified marine plumber. The discharge thruhull may be positioned below the waterline only if the discharge hose has a vented loop fitting installed at least 8 Inch above the waterline at all angles of heel or trim. Although the Jabsco Macerator pump can be installed at any convenient point in the waste discharge system, it is recommended that it be installed as close to the holding tank as possible, this will increase the performance of the pump. It is also recommended that the switch used to control the macerator be mounted close enough to the pump that it can be heard whilst in operation, this will allow the operator to hear a change in pump noise when the unit has finished pumping the tank dry. The pump then should be turned off; this will further increase the life of the pump.
