MH480 Manhole Pump

Product catalog summary

Overview: The MH 480 is a submersible manhole pump designed for mobile wet pit sewer bypass operations. It features a 6-inch flange or hose and operates at 10 HP (7.5 kW), optimized for high volume and low head applications.

Specifications:

Model: MH 480
Power: 10 HP (7.5 kW)
RPM: 1750 (60Hz) / 1450 (50Hz)
Max Amps: 14 (460v) / 16 (400v)
Solids Handling Capacity: 3 inches (75 mm)
Weight: Approximately 490 lbs (223 kg)
Impeller Type: Channel
Max Fluid Temperature: 104°F (40°C)
Max Starts/Stops Per Hour: 15
Max Submergence: 33 feet (10 meters)

Motor: The pump is equipped with a 4-pole induction continuous rated motor featuring a squirrel cage rotor. It includes bi-metallic switches embedded in the stator winding for overheating protection. The stator insulation is class 'H' (180°C).

Power Supply: The pump operates on a 3-phase, 50/60 Hz AC supply and is available in various voltage combinations (208/220/230/380/415/460/575/1000V).

Bearings: The rotor shaft is supported by two ball bearings. The lower bearing is a double row contact type capable of handling high thrust and radial loads, while the upper bearing is a deep groove single row oversized bearing. Both bearings are enclosed with high-temperature grease containing an anti-corrosion additive.

Power Cable: The pump comes with a waterproof and oil-proof rubber-insulated, neoprene-sheathed copper conductor flexible cable, 50 feet (15 meters) in length. The cable type varies by region: SOOW in North America, EPR in the Middle East, and HO7RN in the EU.

Shaft Seals: The pump features compact tandem tungsten carbide/tungsten carbide upper and lower mechanical seals to minimize shaft overhang and deflection, maximizing service intervals. An optional moisture sensor is available to detect seal wear.

Hydraulics: The pump uses single channel impellers that are hydrodynamically balanced to improve flow patterns and reduce clogging.

Cooling: The motor casing has integral cast cooling fins with a large surface area for efficient heat dissipation and low temperature rise. Shrink-fitted stators and short shaft overhang aid in cooling.

Materials of Construction:

Casing/Discharge: Cast Alloy Steel ASTM A487
Impeller: Cast Iron ASTM A48 Class 30 (FG 220)
Shaft: 431 Stainless Steel
Hardware: 304 Stainless Steel
O-Rings: Nitrile Rubber
Mechanical Seals: TC/TC (Upper & Lower)

Surface Treatment: The pump is primed with epoxy and coated with black chloric paint for maximum corrosion resistance, suitable for pH range 6 - 11.

Performance Curve: The document mentions a performance curve for the MH-480 model, indicating its operational efficiency and capacity, but specific data is not provided in the text.

Note: Specifications are subject to change due to continuous product development.
