K2 Pumps CONTRACTOR SERIES 1/2 HP 2in Manual Sewage Pump

Description

Pump raw residential sewage, laundry lint, and wastewater through municipal septic tie-ins. The K2 Pumps CONTRACTOR SERIES 1/2 HP manual sewage pump clears stringy debris without clogging. A 0.5-horsepower oil-filled motor drives a cast-iron vortex impeller. The manual design requires external float switch controls for automated basin management.

Rugged cast-iron forms the motor frame, volute casing, and pump base to resist corrosive sewer gases. The non-clogging cast-iron vortex impeller creates centrifugal fluid vortexes that move 2-inch spherical solids without blade contact. Dual carbon ceramic mechanical seals protect the motor stator from wastewater intrusion. An oil-filled motor housing dissipates heat into surrounding effluent fluids. Stainless steel hardware resists acid rust.

Sewage Waste Hardware Traits

Plumbing contractors evacuate residential sewage collection basins without clogging failures. Heavy cast-iron construction prevents pump movement in high-inflow drainage pits.

• Oil-filled 0.5-horsepower motor operates on standard single-phase 115-volt residential power
• Cast-iron vortex impeller passes spherical sewage solids up to 2-inch diameter
• Heavy cast-iron pump housing dissipates motor heat and resists wastewater corrosion
• Carbon ceramic mechanical shaft seals prevent fluid entry into the motor chamber
• Continuous-duty motor design handles high-frequency start cycles in lift stations
• Tough 20-foot water-resistant power cord allows deep basin electrical connections
• Full 2-inch NPT discharge port connects straight to standard sewage drain piping

Dynamometer Stress Bench Data

Bench testing indicates the motor draws 7.2 Amps on 115-volt lines under a 15-foot dynamic discharge head. Sewage fluid discharge stabilizes at 85 GPM through a 2-inch PVC line. Motor internal oil temperature stabilizes at 132°F after 3 continuous hours of cycling. Sound meters record 54 dBA submerged and 61 dBA in open air.

Field Application Operator Boundaries

You lower this heavy sewage pump into collection pits using the cast-iron top handle. The broad base plate stays stable on sludge-covered sump floors. Do not run this sewage pump without water immersion. Operating the pump dry removes motor cooling and destroys the mechanical shaft seal within minutes.

• Inspect the 2-inch suction port for trapped rags before lowering into lift stations
• Verify check valve operation on the discharge pipe to stop fluid backflow
• Wash the exterior pump housing with clean water after servicing sewer sumps
