2 The /-R series incorporates a cutter mechanism consisting of one or two sintered tungsten carbide alloy edges integrated with a channel impeller and a suction cover with a saw-tooth suction port. The cutter mechanism cuts incoming fibrous materials into pieces, permitting smooth passage of them. The impeller and suction cover of the -R series is made of high-chromium cast iron, ensuring excellent durability and enabling the pump to maintain high performance for an extended period. Motor Protector Each pump up to 7.k as standard has a built in auto-cut, self-resetting ircle Thermal Protector (TP). ntegrated in the motor housing, the TP directly cuts the motor circuit if excessive heat builds up or an overcurrent caused by an electrical or mechanical failure occurs. Miniature Thermal Protector (MTP) is embedded in each winding of the motor. These MTPs are connected in series, and their wires are led out of the motor. Should the winding temperature rise to the actuating temperature, the bimetal strip opens to cause the control panel to shut the power supply. Mechanical Seal The mechanical seal with two seal faces containing silicon carbide (Si) is equipped with the oil chamber. The advantages of the seal are two-fold, it eliminates spring failure caused by corrosion, abrasion or fouling which prevents the seal faces from closing properly, and prevents loss of cooling to the lower seal faces during run-dry conditions which causes the lower seal faces to fail. Oil ifter (Patented) The Oil ifter was developed as a lubricating device for the mechanical seal. Utilizing the centrifugal force of the shaft seal, the Oil ifter forcibly supplies lubricating oil to the mechanical seal and continues to supply the oil to the upper seal faces even if lubricant falls below the rated volume. This amazingly simple device is not only reliably lubricates and cools down, but also retains the stable shaft seal effect and extends the inspection term. Entry mpeller & Suction over Every cabtyre cable has an anti-wicking block at the cable entry section of the pump. This mechanism is such that a part of each conductor is stripped back and the part is sealed by molded rubber or epoxy potting which has flowed in between each strand of the conductor. This unique feature prevents wicking along the strands of the conductor itself. Motor utter Pump Operation The motor is a dry-type, squirrel-cage induction motor, housed in a watertight casing, and conforms to insulation classes B, E or F. n each of these insulation classes, all standard pumps can be used in ambient temperatures up to. Shaft The high-tensile stainless steel shaft used on all pumps is designed to have adequate strength for the transmission of the full load. t is supported by type, high-quality, deep-groove ball bearings. One or two sintered tungsten carbide alloy edges are brazed onto the impeller vane, and they rotate on the serrated part of the suction cover. ncoming fibrous materials are cut up by this mechanism, and this prevents clogging in the pump discharge pipes or valves. UTOMT MODE The Tsurumi automatic model has an integral control circuit and two float switches that operate at a low voltage. t operates automatically in response to the change in water levels. s the pump has a ircle Thermal Protector (TP) integrated into the motor to protect the motor from overload or overheating, it is not required to provide an extra motor protection circuit in the starter panel. This model can be identified by the suffix. Refer to model selection for availability and model numbers. GUDE R FTTNG SYSTEM TOS and TO The TOS / TO is the Tsurumi standard guide rail fitting system. This system connects the pump to and from the piping easily just by lowering and hoisting the pump, allowing easy maintenance and inspection without the need to enter the sump. The auto-alternation model is used along with an automatic model. The combinational use of these two pumps enables each pump to operate alternately without control panel. The auto-alternation model has three floats and can be identified by the suffix. Refer to model selection for availability and model numbers. t is available in the same output range of the automatic pumps. ow the uto-alternation Model orks Operation is enabled by merely connecting the power supply. Primary Operation Float operates, and pump starts to discharge water. MODE NUMBER DESGNTON Start float of pump operates to start water discharge. ater is discharged (water level falls). ater is discharged (water level falls). Stop float of pump operates to end water discharge. t this time, alternation start float of pump rests for one discharge operation. Secondary Operation Stop float of pump operates to end water discharge. t the same time, start float of pump becomes ready for operation. Primary and secondary operation are repeated alternately. Both primary and secondary operations are performed simultaneously when water has risen to an abnormal level.

5 SPE ESSORES FOT STES Tsurumi offers two types of float switches (liquid level sensors). micro-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 micro switch, the M- assures trouble-free operation in the liquid containing much suspended solids and floating scum. Either of the two contacts, normally-open or normally-close, can be selected as required. Model RF- is an economy type float which can detect upper/lower limit 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. TSURUM OPTONS SPE VERSON T GVN ORROSON PROTETON n seawater, a material s resistance to corrosion can be seen clearly. hen metals with different potentials are brought into contact in seawater, only the metal of lower potential corrodes. s the difference in potential increases, the metal of lower potential corrodes faster. s an option, Tsurumi can supply pumps with parts made of higher electric potential metal as the sacrificial anode. SPE VERSON FOR GER TEMPERTURE QUD Standard pumps are designed for continuous running at the maximum ambient temperature of. n addition to these, Tsurumi can provide pumps for operation at higher liquid temperatures upon request. Refitting for operation at higher temperatures involves modification of not only the insulation of motor windings but also several components. Two high-temperature operating models 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 more details. (These special versions are not available for some pump models.) DRY PT VERSON The advantage of dry pit model is that it will not be damaged by flooding, as it is constructed with a submersible pump. Tsurumi can provide the dry pit model as option. The water jacket covers whole part of the motor. t efficiently cools the motor for continuous operations. SPE VERSON T NON-STNDRD MTERS Tsurumi can also provide you with pumps with essential components such as the impeller, pump casing, and the suction cover made of non-standard materials.
