Will Handle sewage, waste, toilet paper, cigarettes, cigars, and all maceratable solids of approximately 1 inch size. 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. Oberdorfer Macerator Pump Head Only, Bronze

Oberdorfer N991 Gear Pump Peo 1/4" Brz Buna  Pump housings and gears are made of top quality bronze, shafts are 303 stainless steel. Bearings are designed of high performance carbon-graphite material selected for wear resistance and long service life.   Gear pumps are positive displacement pumps. Each shaft revolution displaces a definite amount of liquid relatively unaffected by the backpressure in the discharge line. Shaft speed and flow are directly proportional.   Recommended pressure limits are 100 PSI for water and non-lubricants, 150 PSI for oil and other lubricants. The maximum shaft speed is 1750 RPM. Close-coupled gear pumps are normally supplied with a Nitrile lip seal. A lip seal made of fluoroelastomer is available as an option. For a fluoroelastomer Seal, add S5 to the pump model number.   FEATURES Rugged corrosion resistant bronze construction Compact close-coupled design Stainless steel shafts Durable bronze spur gears Process lubricated carbon graphite bearings O-ring cover seal for maximum leak protection Nitrile Lip Seal -standard Easy field assembly to a variety of motor frames For typical DC motor pump units - see N991-32 DC For compact AC motor pump units - see Close Coupled Bronze Adapterless Rotary Gear Pumps For bronze pedestal pumps and mechanical seal styles - see model N1000 DRIVE Close-coupled pumps are mounted directly to the electric motor by means of a suitable adapter bracket. The pump drive shaft is connected to the motor shaft by a flexible coupling.   LIQUIDS & TEMPERATURES These pumps are suitable for all liquids that are compatible with bronze. Most common liquids are water, oil, and mild chemicals in the pH range of 4 to 11. Viscous liquids require reduced shaft speeds of 1150 RPM or lower. (Consult factory.) Liquids containing solids, abrasives, powders, or paint pigments are definitely not recommended for gear pumps. If abrasives are unavoidable, use a very low shaft speed. The recommended liquid temperature range is from 32o F to 140o F for best pump life. If more extreme temperature conditions exist, factory should be consulted. Freezing of water-filled pumps can cause damage and must be avoided. Oils at low temperatures are very viscous requiring a lower speed or extra power.   SUCTION LIFT As a general rule, the suction lift should be kept at an absolute minimum by placing the pump as close to the liquid source as possible. A gear pump in new condition can lift 20 feet of water in the suction line. A foot valve (preferably with built-in strainer) is recommended at the beginning of the suction line. For a first start-up, the pump should be primed to avoid dry running. Minimum size of the suction pipe is the size of the pump inlet port. For longer suction lines (over 3 feet) or for viscous liquids, the pipe should be at least one size or two sizes larger than the pump inlet port.

Oberdorfer Pump 800B Ped Mnt Brz 1 1/4 X 1 Oberdorfer™ centrifugal pumps have a single rotating metal impeller. Liquid enters at the center and is thrown outward radically by centrifugal force. The impeller is not in contact with other pump parts resulting in quiet, efficient, pumping action. The flow produced is not positive which permits the discharge line to be shut off completely without danger of overloading motors or bursting lines. Consequently a relief valve is not required. The liquid flow varies directly as the pump speed--the higher the speed the greater the flow. Horsepower required varies directly as flow and pressure. Maximum horsepower is required with a wide open discharge line. This is the point of maximum flow. With a throttled discharge, the flow decreased at a greater rate than the pressure increases thereby requiring less horsepower at the higher pressures. This is known as an “unloading” feature of the pump.  Silent, efficient, centrifugal pumping is ideal for convenient equipment location in offices, laboratories, public areas, and living quarters. Long trouble-free service life has made centrifugal pumps acceptable for industrial uses or wherever clean or contaminated liquid is to be transferred or handled. The 800B centrifugal pump has external ball bearings isolated from the liquid being pumped. The ball bearings are grease sealed for life requiring no maintenance.     FEATURES Bronze Construction Heavy Duty Ball Bearings Designed for Pulley Drive Mechanical Seal Quiet Operation Handles Contaminated Liquids No Lubrication Required Closed Impeller -- High Discharge Pressure DRIVE The pedestal centrifugal pumps can be direct driven by electric motors and gasoline engines or pulley driven at intermediate speeds as listed in the capacity chart above.    LIQUIDS & TEMPERATURES Because centrifugal pumps are more efficient at higher shaft speeds, pumping of viscous or thick liquids is difficult. It is possible to lose as much as 40% pump performance when attempting to pump liquids of viscosity equal to S.A.E. 30 oil at room temperature. S.A.E. 30 oil at room temperature has a viscosity of 2000 Saybolt Seconds Universal. More viscous liquids are not recommended for centrifugal pumps.   Heavy liquids can be pumped; however, they demand more horsepower in direct ratio to the weight of water. For example, carbon tetrachloride has a specific gravity of 1.6 which means it is 1.6 times heavier than water and the horsepower required is 1.6 times water horsepower.   SUCTION LIFT This centrifugal pump is not self priming. Normally these pumps must be installed below the liquid level so that the liquid flows to the pump by gravity. However, if a foot valve is used at the beginning of the suction line and all air is bled from the suction line and pump by careful manual priming, these pumps will lift liquid on the suction side up to 15 ft. Such a system is only as positive as the ability of the foot valve to seal and keep the suction line and pump full of liquid. If the foot valve should leak, the pump will not prime.

Oberdorfer 170M Cent Pump Peo Brz 3/4 Ports These Oberdorfer™ centrifugal pumps have a single open vane rotating impeller. Liquid enters at the center and is thrown outward radically by centrifugal force. The impeller is not in contact with other pump parts resulting in quiet, efficient pumping action. The flow produced is not positive which permits the discharge line to be shut off completely without danger of overloading motors or bursting lines. Consequently, a relief valve is not required.   The flow of these pumps can be conveniently controlled by a throttling valve in the discharge line. Horsepower demand will decrease as the pressure increases. Maximum horsepower occurs with a wide open discharge.   The lip seal is Nitrile with stainless steel spring reinforcement on a stainless steel motor shaft. The seal is friction press fit in a machined housing counter bore. Excessive system pressures above 15 PSI are not recommended as the seal could be forced out of the pump housing.   FEATURES Rugged Corrosion Resistant Bronze Construction Compact & Light Nitrile Lip Seal STD; Optional fluoroelastomer Lip TEFC Motors With Corrosion Resistant Passivated 316 SS Shafts 1/10 HP Permanent Magnet 12V, 24V, 32V DC Motors Rubber Base Grommets For Vibration Dampening Insulated Leads 1/13 HP Permanent Magnet 12V DC Motor (A95) Ideal for:   Marine Air Conditioning Engine Block Temperature Control Radiator & Heat Exchanger Circulation Baitwell Circulation DRIVE One of the outstanding features of this pump and motor unit is its compact D.C. motor size. Although small, adequate motor power is available.  Motors are available in 12, 24 and 32 VDC.   LIQUIDS & TEMPERATURES This pump is more than capable of pumping water, water solutions, and a wide range of commercial chemicals. Viscous liquids with a maximum viscosity of 2000 Saybolt Seconds Universal can be pumped. However, when pumping viscous liquids (as compared with water) a reduction in flow and pressure occurs and the required horsepower increases.  Liquids heavier than water require additional horsepower in direct proportion to the increase in specific gravity.  Questions about the chemical compatibility of special liquids should be referred to the factory.      SUCTION LIFT These pumps are not self priming.  They must be installed below the liquid level so that the liquid flows to the pump by gravity (flooded suction).  However, if a foot valve is used at the beginning of the suction line, and all air is bled from the pump by manual priming, the pump will lift on the suction side up to 15 feet.  Such a system relies entirely on the non-leaking foot valve for starting capability.
