Tsurumi KTZ-15H Heavy-Duty Dewatering Pump – 2 HP, Cast Iron, 50 mm
This is an imported Tsurumi KTZ-15H submersible dewatering pump from Tsurumi's KTZ series, the Japanese manufacturer's flagship line of heavy-duty drainage pumps. It has a 1.5 kW (2 HP) motor and a 50 mm (2 inch) outlet, and Tsurumi rates it at 0.25 m³/min (15,000 LPH) at 16.5 m head. It is supplied by Standard Machinery in Imported, Refurbished & Tested condition, with the motor rewound for 440 V, 3 phase.
Unlike lightweight aluminium site pumps, the KTZ series is built with a cast iron body and a high-chrome cast iron impeller, designed to keep working in abrasive water carrying sand and silt. In Tsurumi's current range, the comparable 50 mm, 1.5 kW model is the KTZ21.5.
What Makes the KTZ Series Different
- Cast iron construction: Pump casing and motor frame in cast iron for durability in harsh site conditions
- High-chrome impeller: Semi-open impeller in high-chromium cast iron, with a ductile iron suction cover, for wear resistance in sandy water
- Double silicon carbide seals: Mechanical seals isolated in an oil chamber to protect against abrasion
- Convertible performance: Tsurumi designed the series so head or volume can be changed by swapping the impeller and wear plate
- Self-cooling design: Pumped water passes through the casing to help cool the motor

Voltage & Power Note
The motor has been rewound for 440 V, 3 phase, which suits standard Indian 415–440 V industrial supply. The original Tsurumi nameplate is retained and still shows the factory rating of 200/220 V, 60 Hz; the 440 V rating applies after our rewinding.
Tsurumi's rated duty point of 15,000 LPH at 16.5 m is for 60 Hz operation. On a 50 Hz supply, the pump runs about 17% slower; by the pump affinity laws, the duty point shifts to roughly 12,500 LPH at about 11.5 m. Use a DOL starter with overload, phase-failure and earth protection.
Safety Note
- This refurbished unit is not offered as explosion-proof and must not be used in hazardous areas
- Pump water only, including water with sand and silt; not for oil, fuel, solvents or flammable liquids
- Lift and lower the pump by its handle, never by the power cable
- Always connect the earth conductor before use
Maintenance Tips
- Check the seal chamber oil regularly; water in the oil indicates seal wear
- Inspect the impeller and wear plate if output drops; both are replaceable wear parts
- Clean the strainer after working in muddy water
- Check motor insulation resistance before installation
- Inspect the power cable for cuts and damage before each use
- Check running current after installation and set the overload relay accordingly
