|
| Single-phase Portable Water Pumps |
| |
|
| Tsurumi single-phase portable dewatering pumps are compact and lightweight, so they are very easy to handle and carry. These pumps have many different motor outputs ranging from 0.1 to 2.2kW and thus are suitable for a wide range of applications including general pumping and drainage, slurries, residues and household uses. |

LB Series: |
| |
| ▸ |
The LB-series is a submersible single-phase portable drainage pump. Every LB model is slim design enough to be accommodated in an 8-inch pipe. The discharge direction of LB-400 and Lb-800A is selectable between vertical and inclined, which prevents folding or bending of the discharge hose. |

HS Series: |
| |
| ▸ |
The shaft-mounted agitator of HS series prevents the air lock that tends to take place on vortex or semi-vortex pumps. The side discharge with spiral design allows smoother passage of the sucked solid matters. |

FAMILY Series |
| |
| ▸ |
In addition to the 25mm hose coupling, FAMILY series also comes with an easy-to-attach 15mm hose coupling as a standard accessory. The FAMILY-A pump with a cylindrical float switch reduces power consumption and extends operating life. |

|
| KTZ Dewatering Pump Series |
| |
|
| The KTZ series are submersible three-phase cast iron high head heavy-duty drainage pumps. |
| |
|
| • |
Features: |
| |
| ▸ |
The cast iron body with high-chromium cast iron impeller enables it to withstand demanding conditions found in construction, aggregate and mining applications. |
| ▸ |
Dual silicon carbide mechanical seals are isolated in the oil chamber to protect the seal faces against abrasion and corrosion. |
| ▸ |
Pumps with a 7.5 to 15kW motor incorporate seal pressure relief ports to reduce the premature wear and failure of mechanical seals in higher pressure applications. |
| ▸ |
The discharge direction is selectable between vertical and inclined, which prevents folding or bending of the discharge hose. |

|
| Submersible Sewage Pump with Channel Impeller - B Series |
| |
|
| The B-series pumps are submersible channel impeller pumps designed for handling raw sewage, wastewater and heavy-duty industrial applications, where the pump is subject to complete submersion and requires outstanding reliability. The B-series offers long life in both continuous and intermittent sump applications. Discharge bores from 50 to 800mm are available. |
| |
|
| • |
Features: |
| |
| ▸ |
The motor is a dry-type, squirrel-cage induction motor, housed in a watertight casing. |
| ▸ |
The impeller is semi-open or shrouded type with one or two vanes. It has a wide channel extending from inlet to exit, which allows the pump to pass the solid matters from inflow to discharge with minimal blockage. |
| ▸ |
The high-tensile stainless steel shaft used on all pumps is designed to have adequate strength for the transmission of the full load. |
| ▸ |
The patented Oil Lifter was developed as a lubricating device to provide stable lubrication for the mechanical seal. |
|
| |
|
| Submersible Sewage Pump with Cutter Impeller - C Series |
| |
|
| The C-series pumps are heavy-duty submersible cutter pumps for sewage and wastewater applications, where the pump is subject to clogging from oversize material. They have a combination of impeller vane with brazed sintered tungsten carbide alloy edge and a suction cover of serrated shape. This cutting mechanism cuts incoming fibrous material into pieces, permitting smooth passage of fibrous material. |

Features: |
| |
| ▸ |
Anti-wicking cable entry helps to prevent water incursion due to capillary action should the cable sheath be damaged or the end of cable submerged. |
| ▸ |
Dual mechanical seals with silicon carbide faces is isolated in the oil chamber where a clean, non-corrosive and abrasion-free lubricating environment is maintained. |
| ▸ |
Oil seal is used as a “Dust Seal”, which protects the mechanical seal from abrasive particles. |
| ▸ |
For models with 7.5 kW and below, circle thermal protectors directly cut the motor circuits if excessive heat builds up or overcurrent occurs in the motor. For models with 11kW and above, miniature thermal protectors react to excessive heat caused by dry-running. The bimetal strip opens to cause the control panel to shut the power supply. |
