Submersible Wastewater Pumps SF Series

Submersible wastewater pumps sf series is a type of effluent pump that is made of cast iron and has a compact design. This pump uses a semi-open impeller and is primarily designed to handle high-head pumping tasks as well as defoaming duties at wastewater treatment plants. Its efficient design allows it to effectively manage the flow of effluent, which is an important aspect of maintaining efficient wastewater treatment processes. Overall, the SF-series effluent pump is a reliable and effective solution for handling the demands of wastewater treatment plants.

FLOAT SWITCHES

Model MC-2 is a heavy-duty type float switch with a shock absorber.
Having equipped with a high grade micro switch, the MC-2 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-5 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.

TOK GUIDE RAIL FITTING SYSTEM

Tsurumi provides TOK-type guiderail fitting system, as an option, for Model 50SF2.75. The fittings con-nect/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

Special Accessories sf

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.
