TSURUMI OPTIONS
SPECIAL VERSION WITH GALVANIC CORROSION PROTECTION
In sea water, the effect of galvanic corrosion is more serious than that of ordinary corrosion. When two kinds of metals are dipped
into an electrolytic liquid, a battery phenomenon occurs due to the difference in the electric potential of the two metals. In this case,
the metal having the higher potential corrodes first. As an option, Tsurumi can supply pumps with parts made of higher electric
potential metal as the sacrificial anode.

SPECIAL VERSION FOR HIGHER TEMPERATURE LIQUID
Standard pumps are designed for continuous running at the maximum ambient temperature of 40°C. In 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 60 for operation in liquids up to 60°C and the Rank 90 for
operation in liquids up to 90°C. Consult your dealer for more details. (These special versions are not available for some pump
models.)

DRY PIT VERSION
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 for the whole range of U/UZ-series pumps. The water jacket covers whole part of the
motor. It efficiently cools the motor for continuous operations.

SPECIAL VERSION WITH NON-STANDARD MATERIALS
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. Select from stainless steel, chromium iron and bronze to suit your specific requirements. Consult
your dealer for more details.

SPECIAL ACCESSORIES
FLOAT SWITCHES
Tsurumi offers two types of float switches (liquid level sensors). A micro-switch is incorporated in both types.
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, normallyopen 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.

We reserve the right to change the specifications and designs for improvement without prior notice.
