Subersible Sewage Pups Printed on a recycled paper with soy ink - evidence of our coitent to the environent enities fro Technology for People and The Earth
Featuring a vortex ipeller recessed in the widely opened pup casing interior, the U and UZ pups can handle sewage with large solids without clogging or winding. Entry Every cabtyre cable has an anti- wicking block at the cable entry section of the pup. This echanis is such that a part of each conductor is stripped back and the part is sealed by olded rubber or epoxy potting which has flowed in between each strand of the conductor. This unique feature prevents wicking under the strands of the conductor itself. Protector Each pup up to. as standard has a built in auto-cut, self-resetting ircle Theral Protector (TP). ntegrated in the otor housing, the TP directly cuts the otor circuit if excessive heat builds up or an overcurrent caused by an electrical or echanical failure occurs. GUDE R FTTNGS We recoend using the Tsurui guide rail fitting syste with pups. This syste connects the pup to and fro the piping easily just by lowering and hoisting the pup, allowing easy aintenance and inspection without the need to enter the sup. TOS The TOS guide rail fitting syste is ade of cast iron and is copatible with Tsurui cast- iron pups. Refer to the specification table for the correct odel nuber prefixed with TOS. TS This copact guide rail fitting syste is ideal for installing on prefabricated lift stations. ts discharge flange is copatible with ajor flange standards including NS lb, S PN, and DN PN. Four odels are available and can be used on Tsurui cast-iron pups in the through discharge bore range. TOK Made of high quality resin, the TOK is designed for light-weight, sall pups. Rubber bellows attached to the guide hook are inverted to the duckfoot bend when the pup starts operating. This eliinates leakage at the seal even if a light-weight pup is used in cobination with the TOK. The TOK can be used with the U series pups of.kw through.kw with axiu discharge bore of. Mechanical Seal ll pups are provided with a Silicon arbide dual inside echanical seal that is located copletely out of the pupage, running in an oil-filled chaber. The advantages of this seal are two-fold, it eliinates spring failure caused by corrosion, abrasion or fouling which prevents the seal faces fro closing properly, and prevents loss of cooling to the botto seal faces during run-dry conditions which causes the botto seal to fail. Oil ifter (Pat. Pending) Utilizing the rotational energy of the shaft seal, the Oil ifter forcibly supply lubricating oil to the echanical seal. t continues to supply the lubricant to the top seal faces even if lubricant falls below the rated volue. This aazingly siple device not only turns wasted energy into added protection but also doubles the life expectancy of the echanical seal and also the aintenance ter. Oil ifter Mechanical Seal Oil The vortex ipeller is recessed in the upper part of the pup casing. Sewage is puped out by the whirlpool action induced by the ipeller. eing coupled with a wide pup casing, large solids and fibrous atters can be puped out without obstruction. OMPOSTON OF TE MODE NME UZ. S ore in illieters Nae of the Series Sub ode for the type None : none-auto type : utoatic type W : uto-alternation Miniature Theral Protectors (MTPs) are ibedded in the winding of the pups of star delta starting. These MTPs are connected in series, and their wires are led out of the otor. Should the winding teperature rise to the actuating teperature, the bietal strip opens to cause the control panel to shut the power supply. The otor is dry type, squirrel cage induction otor, housed in a cast iron, watertight casing, and confors to insulation class of E or F. n each of these insulation classes, all standard pups can be used in the axiu abient teperature of. Shaft The high tensile stainless steel used on all pups is designed to have an adequate strength for the transission of the full load. The shaft is supported by type, high quality, deep groove ball bearings. None : -phase S : Single-phase Rated otor output in Kilowatts Nuber of poles of the UTOMT TYPE The Tsurui autoatic type pup has an integral control circuit and two float switches operated at a low voltage. The pup has an auto-cut, self resetting ircle Theral Protector (TP) integrated into the otor to protect the otor fro overload or overheating. This type can be identified by the suffix "". Refer to the specification table for availability and odel nubers. UTO-TERNTON TYPE n addition to standard autoatic pups, Tsurui offers auto-alternation type pups. utoatic alternation operation is achieved by cobining a parent pup (three floats) with a standard autoatic pup (two floats). This enables each pup to operate alternately without the aid of a control panel. ow the uto-alternation Type Works Operation is enabled by erely connecting the power supply. Priary Operation Float operates, and pup starts to discharge water. Start float of pup operates to start water discharge. The pup ends priary operation, and stops operating. Water is discharged (water level falls). Water is discharged (water level falls). Stop float of pup operates to end water discharge. t this tie, alternation start float of pup rests for one discharge operation. Secondary Operation Stop float of pup operates to end water discharge. t the sae tie, start float of pup becoes ready for operation. Priary operation and secondary operation are repeated alternately. oth priary and secondary operations are perfored siultaneously when water has risen to an abnoral level. The parent pup can be identified by the identification "W".uto-alternation type pups are available in the sae output range as standard autoatic pups.

Material PV hloroprene Rubber SPE VERSON WT GVN ORRSON PROTETON n sea water, the effect of galvanic corrosion is ore serious than that of ordinary corrosion. When two kinds of etals are dipped into an electrolytic liquid, a battery phenoenon occurs due to the difference in the electric potential of the two etals. n this case, the etal having the higher potential corrodes first. s an option, Tsurui can supply pups with parts ade of higher electric potential etal as the sacrificial anode. SPE VERSON FOR GER TEMPERTURE QUD pups are designed for continuous running at the axiu abient teperature of. n addition to these, Tsurui can provide pups for operation at higher liquid teperatures upon request. Refitting for operation at higher teperatures involves odification of not only the insulation of otor windings but also several coponents. Two high-teperature operating odels are available - the Rank for operation in liquids up to and the Rank 9 for operation in liquids up to 9. onsult your dealer for ore details. (These special versions are not available for soe pup odels.) DRY PT VERSON TSURUM OPTON The advantage of dry pit type pup is that it will not be daaged by a flooding of water, as it is constructed by a subersible pup. Tsurui can provide dry pit type pups as option for larger pups in the UZ range pups. Durable otor with effective water cooling jacket assures the pup continuous running without overheating. SPE VERSON WT NON-STNDRD MTERS Tsurui can also provide you with pups with essential coponents such as the ipeller, pup casing, and the suction cover ade of non-standard aterials.

SPE ESSORES FOT SWTES Tsurui offers two types of float switches (liquid level sensors). icro-switch is incorporated in both types. Model M- is a heavy-duty type float switch with a shock absorber. aving equipped with a high grade icro switch, the M- assures trouble-free operation in the liquid containing uch suspended solids and floating scu. Either of the two contacts, norallyopen or norally-close, can be selected as required. Model RF- is an econoy type float which can detect upper/lower-liit water levels with single float. The snap on-off action ensures stable operation in clean or waste water containing suspended solids or oil and fat.
