General Dewatering Pumps |
| Category | Model | Pole | Discharge Bore ( mm ) |
Motor Output ( kW ) |
| General Dewatering | LB | 2 | 50(80) | 0.48 - 0.75 |
 |
The LB-series is a single-phase, lightweight and compact dewatering pump. Because of its slim design, it fits in an 8" casing. Adoption of semi-vortex pump design enables it to maintain the original pump performance for an extended period even if the impeller becomes worn. The discharge direction is selectable between top and horizontal, which prevents folding or bending of the discharge hose. Automatic model is accompanied by a level control unit having timer function that eliminates malfunction caused by rough water surface.

| General Dewatering | LB-1500 | 2 | 50(80) | 1.5 |
 |
The LB-1500 is one of the LB-series slimline single-phase models and also fits in an 8" casing. The pump has a built-in starting capacitor so that no special starter is required. The simple structure makes it easy to disassemble and reassemble.

Motor Output ( kW ) |
| General Dewatering | HS | 2 | 50 ･ 80 | 0.4 ･ 0.75 |
 |
The HS-series is a single-phase, portable dewatering pump having a spiral pump casing that allows sand and silt-laden water to pass through the pump easier than any other pumps of this class. The shaft-mounted agitator prevents "Air Lock" that tends to take place on vortex pumps.

| General Dewatering | NK | 2 | 50 | 1.5 ･ 2.2 |
 |
The NK-series is a KTV-based single-phase dewatering pump. The side-flow, top-discharge design assures efficient motor cooling even when it operates with it's motor exposing in air. Semi-vortex pump design is adopted for maximum durability and maintaining pump’s performance. The pump has a built-in starting capacitor.

Motor Output ( kW ) |
| General Dewatering | KTV KTVE (Automatic Type) |
2 | 50 ･ 80 | 0.75 - 5.5 |
 |
The KTV-series is a compact type, three-phase dewatering pump. Use of die-cast aluminium and synthetic rubber makes the pump lightest in weight among the Tsurumi’s three-phase contractors pumps. This semi-vortex pump minimizes the fear of startup failure resulted by impeller blockage. The pump’s lower part can be disassembled with a single wrench to facilitate maintenance services. Automatic model incorporates a level control unit having a timer function that eliminates malfunction caused by rough water surface.

| Category | Model | Pole | Discharge Bore ( mm ) |
Motor Output ( kW ) |
| General Dewatering | KTZ | 2 | 50 - 150 | 1.5 - 11 |
 |
The KTZ-series is a three-phase, cast iron made, high head dewatering pump. The cast iron pump body presents a different way of top durability that cannot be obtained by aluminium body pumps. A choice is possible between high head but small volume version and large volume but low head version in every motor size.

| Category | Model | Pole | Discharge Bore ( mm ) |
Motor Output ( kW ) |
| General Dewatering | KRS | 4 | 80 - 250 | 2.2 - 22 |
 |
The KRS-series is a three-phase, cast iron made, large volume and heavy-duty dewatering pump operated by 4-pole motor. The KRS, coupled with 4-pole motor, represents Tsurumi multipurpose pumps for reliability, ruggedness and durability.

Motor Output ( kW ) |
| General Dewatering | KRS (Energy-Saving Type) |
4 | 100 - 200 | 3 - 9 |
 |
This is another KRS-series pump but is designed and developed for low head applications. In combination with specially developed motor, this KRS-series brings energy saving at low head pumping.

| Category | Model | Pole | Discharge Bore ( mm ) |
Motor Output ( kW ) |
| General Dewatering | LH | 2 | 100 - 200 | 15 - 110 |
 |
The LH-series is a three-phase, cast iron made, high head dewatering pump. The pump can be installed in a narrow place, as it is cylindrical and the discharge flange is located at the top of the pump. The center-flange construction enables the pump to be installed true to be the center of gravity and to be lifted up/down without disconnecting it from piping.

| Category | Model | Pole | Discharge Bore ( mm ) |
Motor Output ( kW ) |
| General Dewatering | GSZ-4 | 4 | 150 - 250 | 37 - 75 |
 |
The GSZ-4-series is a high head and large volume dewatering pump driven by 4-pole motor. The pump has a water jacket, surrounding the motor casing, by which a portion of pumped water is allowed to flow around the motor on its way to the side discharge, which permits the pump to operate at low water levels for extended period of time.
