214M

This all bronze rubber impeller pump is used for sewage transfer from toilets to holding tanks and for pump-out and disposal from holding tanks. It’s solid, corrosive resistant design can handle sewage, waste, toilet paper, cigarettes, cigars, and all solids maceration of approximately 1 inch size. Macerator WILL NOT handle fruit pits, hard plastic utensils, prophylactics, cloth or sanitary napkins.

For optimal performance the impeller and seal must be replaced using these guidelines: 

The impeller must be replaced if it is worn out or has been damaged by debris or by running the pump dry. Symptoms of a defective impeller are low pumping pressure and low flow. To replace the impeller, remove screws and cover. Remove macerator wheel, plate and gaskets. Pull out the impeller with needle nose pliers or two screwdrivers. Be careful not to dent the pumping chamber with these tools. When inserting new impeller, line up flat on impeller with flat on the shaft. Use oil on shaft and avoid forcing the impeller onto the shaft.

The impeller should also be removed for storage periods to prevent the blades from taking a permanent set.

If water drips from the weep hole or from the area where the shaft exits the pump, the seal is defective and must be replaced. While the Polytetrafluoroethylene (PTFE) barrier seal provides a first line of defense, prolonged running of the pump with a leaky seal can destroy the ball bearings resulting in catastrophic pump failure and motor

shut-down. For seal replacement, the pump must be removed from the motor and disassembled in order to gain access to the seal area. Lip seals must be pushed out of their press-fitted position and new seals pressed into place using a sealant on the outside of the lip seal housing. Refer to exploded view drawings for seal location and part numbers for ordering purposes.

DRIVE

Flexible impellers generate high rubbing friction unless lubricated by liquid being pumped. Lack of liquid will cause impellers to burn up. It is important to avoid dry start-ups. Usually sufficient liquid for a “wet” start is trapped in pump piping system during normal usage. If not, inject water or lubricating oil thru inlet or outlet ports or thru pipe plug openings on pump castings. (Caution - do not remove flush panhead screw holding pump body cam in position - see exploded view). It is most important to insure a “wet” start when a pump is being used for the first time in a new installation or after a prolonged storage period when all liquid has evaporated. Any plugs removed from pump body or cover must be re-tightened prior to start up. 

IMPORTANT - DO NOT RUN DRY

LIQUIDS & TEMPERATURES

Liquids compatible with neoprene can be pumped including fresh and salt water solutions and mild chemicals. Do not pump severe solvents or acids. When possible, flush pump with fresh water after each usage. Nitrile impellers can handle oil contaminated water and kerosene at reduced impeller service life. Extremes of cold and heat will affect impeller life. Limits of 40o to 180o should be observed. Do not allow liquid in pump to freeze. Drain pump by loosening cover screws. Use methyl alcohol based anti-freeze compounds such as Zerex, Shell Zone, Pyro Permanent, Permagard, or Dowgard.

SUCTION LIFT

Pump Inlet (suction)- All suction connections must be air tight and as short as possible to achieve lift. A suction lift of up to 4 feet is possible under ideal conditions. Because the suction line for sewage handling is of large size (1 1/2” pipe) a large volume of air must be evacuated to create vacuum and suction lift. This is why a “wet” start is essential to prevent overheating and burning of the impeller during the air evacuation and suction period.
