Single-phase Portable Pumps FAMILY Series

Single-phase Portable Pumps FAMILY Series are compact and lightweight, so they are very easy handle and carry. Available in an extensive lineup of motor outputs ranging from 0.1 to 2.2kW, these pumps are suited for a wide range of applications besides general pumping and drainage, including slurries, residues and household uses. Though compact in size, these pumps pack a host of original technologies that Tsurumi has tested and proven over many years

Tsurumi has been manufacturing construction dewatering pumps for more than 50 years. This has led to numerous technologies and know-how
for improving the durability and maintainability of pumps in the rental and construction markets where rugged work environments demand heavy-duty specifications. All of Tsurumi’s pumps are designed and built to be durable and reliable so as to serve users dependably.

Motor Cooling & Dicscharge Design

Top Discharge, Flow-Thru Design
(LB , LB-A , LSC , FAMILY , FAMILY-A)
This design provides maximum motor cooling efficiency allowing continuous operation at low water levels and extended dry-run capability, and also allows the shape of the pump to be cylindrical and slim for installation in a well casing for deep well dewatering.

Top Discharge, Side Flow Design
(NK)
This design assures efficient motor cooling even if the pump runs with its motor exposed to air, and also allows the overall diameter of the pump to be reduced for installation in confined spaces.

Side Discharge, Spiral Design
(HS , HSZ , HSD , HSR)
The pump has a spiral pump casing that facilitates smoother passage of foreign objects like mud and soil contained in the pumped liquid. It is a simple and practical design that facilitates inspection and repair work.

Residue Drainage

HSR
Can pump water as shallow as 5mm from the bottom of the pump and drain water to 1mm in depth.

LSC
Can drain water to 1mm in depth. A valve seat and swing check valve prevent suctioned water from backflowing.

LSP
Can pump pooled water from shallow recesses using the suction attachment. A syphon breaker mechanism prevents backflowing and the seal water from draining out.

FAMILY option
At tac hing the opti onal resi due adapter to the pump casing allows draining to 1mm in depth.
* excluding automatic model

Automatic Operation

Float Switch (HSZ / FAMILY-A)

The automatic model only operates when sufficient water is present. It not only reduces power consumption but also extends the life of wear parts of the pump as it eliminates dry-running that causes early wear-out.

FAMILY -Domestic Pumps-

The FAMILY/FAMILY-A series are submersible single-phase portable drainage pumps. In addition to the 25mm hose coupling, it 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. Moreover, it can be used as a residue pump and drain water to 1mm in depth by attaching the optional residue adapter to the pump casing (for FAMILY-12, standard model only).

Automatic Operation (FAMILY-A)

Optional Accessory

Residue Adapter (for FAMILY-12, standard model only)

Attaching the optional residue adapter to the pump casing allows draining to 1mm in depth.

As standard specification, residual
water by 12mm can be drained.

With residue adapter, residual
water by 1mm can be drained.

Structure

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.

1.Anti-Wicking Cable Entry
Prevents water incursion due to capillary action should the cable sheath be damaged or the end of cable submerged. Also prevents moist air from infiltrating the motor housing and condensation from forming inside the housing due to temperature differences between the housing and outside air.

2. Motor Protector
MTP (0.48kW and below)
Detects excess heat, therefore, protecting the pump against overheating and dry-running.
CTP (0.55kW and above)
Directly cuts the motor circuit if excessive heat builds up or overcurrent occurs in the motor.

3.Dual Inside Mechanical Seals with Silicon Carbide Face
Inside Mechanical Seal with Silicon Carbide Face (FAMILY)
Isolated in the oil chamber where a clean, non-corrosive and abrasion-free lubricating environment is maintained. Compared with the water-cooled outside mechanical seal, it reduces the risk of failure caused by dry-heating and adhering matter. The silicon carbide provides 5 times higher corrosion, wear and heat resistance than the tungsten carbide.

4.Oil Lifter
* Not available for FAMILY
Provides lubrication and cooling of the seal faces down to 1/3 of normal oil level, thus maintaining a stable shaft sealing effect and prolonging seal life longer. The Oil Lifter is Tsurumi original design.

5.V-Ring / Oil Seal (excluding HS(Z/R)2.4S, FAMILY)
Used as a “Dust Seal”, they protect the mechanical seal from abrasive particles.

6.Cable Clip (excluding NK3-22L, LSP, FAMILY)
Prevents unexpected water incursion that can occur if the cable is damaged, by protecting the cable against the tugging and rough handling found at construction sites.

7.Agitator
For HS and HSZ
Prevents the air lock that tends to take place on vortex or semi-vortex pumps.
For HSD
Assists the pump in sucking and transferring bentonite slurry, slime, mud, and water with high sand content.

8.Resin-made Stand (HS / HSZ / HSD)
Rubber Stand (HSR / LSC / LSP)
Prevents scratching of floor surface.

9.Multi-Directional Hose Coupling (LB / LB-A / HSR / LSC)
Can be configured for inclined or vertical discharge, allowing for smoother installation.
