Special Accessories Tsurumi Float Switch Model MC-2 is a heavy-duty float switch with a shock absorber. Equipped with a high-grade microswitch, the float assures troublefree pump operation in the sewage or liquid containing suspended solids and floating scum. The MC-2 has both normally open and normally close contacts as standard. You can select either of the two contacts as required. Model RF-5 is an economy float switch which can detect upper/ lower limit water levels with a single float. The snap on-off action ensures stable pump operation in the clean or waste water containing suspended solids or oil and fat. SF TOK Guide Rail Fitting System Tsurumi provides TOK-type guide rail fitting system, as an option, for Model 50SF2.75. The fittings connect/separate the pump to/from piping only by lifting up and down the pump; no need to enter the sump for maintenance. The TOK is supplied with the following contents: • Lifting Chain 4m (with Shackles) • Guide Support (with Bolts & Nuts) • Guide Hook • Duckfoot Bend Tsurumi Options Special Version with Galvanic Corrosion Protection In seawater, a material’s resistance to corrosion can be seen clearly. When metals with different potentials are brought into contact in seawater, only the metal of lower potential corrodes. As the difference in potential increases, the metal of lower potential corrodes faster. As an option, Tsurumi can supply pumps with parts made of higher electric potential metal as the sacrificial anode. Special Version for High Temperature Liquid Standard pumps are designed for continuous running at a maximum ambient temperature of 40°C. In addition to these, Tsurumi can provide pumps for operation at higher liquid temperature upon request. Refitting for operation at higher temperature involves modification of not only the insulation of motor windings but also several components. Two high-temperature operation models are available - the Rank 60 for operation in liquid up to 60°C and the Rank 90 for operation in liquid up to 90°C. Consult your dealer for more details. ( These special versions are not available for some pump models.) Special Version with Non-standard Materials Tsurumi also offers pumps with essential components, such as the impeller, pump casing and suction cover, made of non-standard materials. Select from stainless steel, chromium iron and bronze to suit specific requirements. Please consult your dealer for more information. Product images and specifications may differ from actual products due to improvements. The OO series and model OO are indicated with our series/model codes in this catalog.
