SINGLEPSE PORTLE DEWTERING PUMPS Tsurui singlephase portable dewatering pups are copact and lightweight, so they are very easy handle and carry. vailable in an extensive lineup of otor outputs ranging fro. to., these pups are suited for a wide range of applications besides general puping and drainage, including slurries, residues and household uses. Though copact in size, these pups pack a host of proprietary technologies that Tsurui has tested and proven over any years, including the antiwicking cable, inside echanical seal with silicon carbide face and Oil Lifter*, etc. dditionally, key coponents that are prone to wear are ade of durable aterials and pups as a whole are designed for continuous duty. For these reasons, Tsurui singlephase portable pups are a popular choice at civil engineering, construction and other work sites that deand high reliability. * excluding FMILYseries Tsurui has been anufacturing construction dewatering pups for ore than years. This has led to nuerous technologies and knowhow for iproving the durability and aintainability of pups in the rental and construction arkets where rugged work environents deand heavyduty specifications. ll of Tsurui s pups are designed and built to be durable and reliable so as to serve users dependably.

Structure 9 9 L S LSC ntiwicking Entry Prevents water incursion due to capillary action should the cable sheath be daaged or the end of cable suberged. lso prevents oist air fro infiltrating the otor housing and condensation fro foring inside the housing due to teperature differences between the housing and outside air. Protector MTP (. and below) Detects excess heat, therefore, protecting the pup against overheating and dryrunning. CTP (. and above) Directly cuts the otor circuit if excessive heat builds up or overcurrent occurs in the otor. Dual Inside Mechanical Seals with Silicon Carbide Face Inside Mechanical Seal with Silicon Carbide Face (FMILY) Isolated in the oil chaber where a clean, noncorrosive and abrasionfree lubricating environent is aintained. Copared with the watercooled outside echanical seal, it reduces the risk of failure caused by dryheating and adhering atter. The silicon carbide provides ties higher corrosion, wear and heat resistance than the tungsten carbide. VRing / Oil Seal (excluding S(Z/R).S, FMILY) Used as a Dust Seal, they protect the echanical seal fro abrasive particles. Clip (excluding NKL, LSP, FMILY) Prevents unexpected water incursion that can occur if the cable is daaged, by protecting the cable against the tugging and rough handling found at construction sites. gitator For S and SZ Prevents the air lock that tends to take place on vortex or seivortex pups. For SD ssists the pup in sucking and transferring bentonite slurry, slie, ud, and water with high sand content. Resinade Stand (S / SZ / SD) Rubber Stand (SR / LSC / LSP) Prevents scratching of floor surface. Oil Lifter [Patented] * Not available for FMILY Provides lubrication and cooling of the seal faces down to / of noral oil level, thus aintaining a stable shaft sealing effect and prolonging seal life longer. 9 MultiDirectional ose Coupling (L / L / SR / LSC) Can be configured for inclined or vertical discharge, allowing for soother installation.

Subersible Slurry Residue Drainage Residue Doestic,. utoatic Operation The autoatic odel only operates when sufficient water is present. It not only reduces power consuption but also extends the life of wear parts of the pup as it eliinates dryrunning that causes early wearout. Electrodes (L) Tsurui has developed a unique autoatic control device utilizing electrodes. The pup stops autoatically in about one inute after the water surface falls below the electric probe. Since this echanis eliinates dryrunning, the pup can reduce power consuption by up to percent copared with nonautoatic pups (Tsurui coparison). It also prevents chattering caused by a turbulent water surface and extends operating life. Electrode Control Device utoatic Operation L (Electrodes) SZ (Float) FMILY (Cylindrical Float) Float Switch Float Switch Float Switch (SZ / FMILY) Page No. 9 This autoatic operation syste is controlled by a float switch. When the water level rises and raises the float switch to a preset level, the switch turns on, and the pup starts. When the water level lowers to the preset level, pup operation stops. Cooling & Dicscharge Design SZ FMILY Top, FlowThru Design This design provides axiu otor cooling efficiency allowing continuous operation at low water levels and extended dryrun capability, and also allows the shape of the pup to be cylindrical and sli for installation in a well casing for deep well dewatering.

Top, Side Flow Design This design assures efficient otor cooling even if the pup runs with its otor exposed to air, and also allows the overall diaeter of the pup to be reduced for installation in confined spaces. Side, Spiral Design NK LSP Can pup pooled water fro shallow recesses using the suction attachent. new syphon breaker echanis prevents backflowing and the seal water fro draining out. FMILY option ttaching the optional residue adapter to the pup casing allows draining to in depth. The pup has a spiral pup casing that facilitates soother passage of foreign objects like ud and soil contained in the puped liquid. It is a siple and practical design that facilitates inspection and repair work. S SZ SD SR TSURUMI PUMP TSURUMI PUMP
