This macerator pump has Stainless Steel wearplates, with a Stainless Steel Cutter Plate that reduces the particle size to 1/8 Inch (3.17 mm) maximum. The Jabsco 18690-0000 AC macerator pump unit is the ideal answer to waste handling problems for marine, recreational vehicle and domestic uses. The macerator section grinds waste down to a particle size of 1/8 Inch maximum so it can be pumped easily through a 1 Inch hose discharge line. The pump is self-priming, permitting the unit to be mounted above or below the tank in a convenient location. For optimal efficiency, locate pump as close to waste source as practical. Empties a 30 gallon holding tank in only 3 minutes. The 18690-0000 waste pump will macerate and pump all waste and tissue normally found in marine waste systems. It will NOT handle hard solid objects, sanitary napkins or rags. 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 14.0 GPM, and is self-priming to a six 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 has been designed to handle waste, toilet tissue, and facial tissue. It will also handle solids such as filter tip cigarettes, cigars and chunks of soft fruits or vegetables less than 1 Inch in size. It will NOT pump solid objects like peach pits, rags, or sanitary napkins. The holding tank and pump should be flushed with several gallons of water after each pumpout. INSTALLATION The pump should be mounted upright so the motors bearing lube channels are accessible and to prevent the oil from draining out of them. For optimal efficiency, locate pump as close to waste source as practical. Ideally, if connected to the bottom of the holding tank, the hose length should be long enough so the hosetopump connection can be raised above the maximum liquid level should service be needed when the tank is full. Use 11/2 Inch ID noncollapsible suction hose. Attach suction hose to the inlet port and secure it with a quality marine grade hose clamp. All suction connections must be airtight and free of sharp bends or restrictions. Use minimum 1 Inch ID contractors hose for discharge. Be sure adequate voltage and current capacity is available in electrical installation.
