attempting to transfer slurry.
• If the pump is operated beyond the normal-
use range of the soft PVC hose, replace
with a heat-resistant PVC hose. Failure to
do so may result in damage to the hose
leading to chemical solution leaking or
spurting from the hose.
1-3 Notes on Handling
WARNING
• Install the appliance in a location where it will not come into contact with other people
besides the operator.
• Do not operate the pump when your hands are wet. This could result in an electrical shock.
CAUTION
• If the pump is dropped or damaged, please contact TACMINA or your supplying agent. It
may result in an accident or in damage to the product.
• Do not install this pump in a humid or dusty location, as this may lead to electrical shocks or
result in damage to the appliance.
• If anything unusual occurs such as smoke or a burning smell during operation, immediately
stop operation and contact TACMINA or your supplying agent. Failure to do so could result
in fire, electrical shock or damage to the product.
• Do not touch the motor section during operation as its high temperature may burn the skin.
• Before disassembling the pump for maintenance or repair, make sure to turn OFF the power
and confirm that no voltage is supplied to the pump. Also, make sure that the power switch
is not turned ON again during the maintenance or repair work.
• When handling the liquid contact section, be sure to wear protective coverings (rubber
gloves, mask, protective goggles, chemical-resistant overalls etc.) appropriate for the
chemicals being transferred.
• Before maintaining or repairing the pump, release the discharge-side pressure, drain the
chemicals from the liquid-contact section and wash the pump.
• For the joints, hose nuts and hoses, be sure to use only those accessories provided with the
pump or otherwise recommended by TACMINA. The use of unauthorized accessories may
result in an accident or in damage to the product.
• If you forget to open the discharge-side valve or if foreign matter becomes stuck in the
discharge-side piping, the pressure in the piping and pump head may increase beyond the
range indicated in the pump specifications. This may result in the chemicals leaking or
spurting, or in damage to the pump or the piping.
IMPORTANT
• We recommend the installation of a relief valve in the discharge-side piping so that excess
pressure can be released automatically.
• A relief valve-equipped pump head is also available.

4 Structure
4-1 Drive Box Section
4-1-1 SX Type
The SX type pump is composed of the drive box equipped with a vertical four-pole exclusive
motor which is assembled together with the reduction mechanism and the pump head section.
Within this structure, the following parts are assembled.
(1) Worm.wheel Gear
Reduces the motor rotation to 1/14 or 1/28 of its original value.
(2) Eccentric Shaft
Converts rotary motion into reciprocal motion.
(3) Pump Shaft
Transmits reciprocal motion to the diaphragm.
(4) Spring-Return Mechanism
On the suction stroke, this mechanism forces the pump shaft back to ensure that a
constant discharge volume is maintained.
(5) Feed Flow Adjusting Mechanism
Adjusts the feed flow between 0 and 100% during operation.
* In the case that dial scale indication is less than “1”, the discharge amount may become
unstable.

4-1-2 SY Type
The SY type is composed of a drive box which consists of a four-pole general purpose motor
with legs and planetary gear and the pump head section.
* The figure is for a simplex (single head) pump.
Features of the Planetary Gear
(1) High transmission efficiency
(2) Low noise and low vibration
(3) Wide selection range of the reduction
ratio combination
Within this structure, the following parts are assembled.
(1) Eccentric Shaft
Converts rotary motion, reduced by the planetary gear, into reciprocal motion with the
specified amplitude.
(2) Pump Shaft
Transmits reciprocal motion to the diaphragm.
(3) Spring-Return Mechanism
On the suction stroke, this mechanism forces the pump shaft back to ensure that a
constant discharge volume is maintained.
(4) Feed Flow Adjusting Mechanism
Adjusts the feed flow between 0 and 100% during operation.
* In the case that dial scale indication is less than “1”, the discharge amount may become
unstable.
4-2 Pump Head with Relief Valve
If a diaphragm pump (or any reciprocating pump) is operated while the discharge-side piping
is closed, the pressure in the pump head rises to above the rated pressure. If operation
continues in this state, the pump drive mechanism may be damaged or the discharge-side
piping ruptures. In such a case, if a pump head with a relief valve is used, the pump, piping
and peripheral parts can be protected without the need to install a relief valve in the
discharge-side piping.

4-2-2Pressure Adjustment
Remove the cap 1and turn the pressure adjusting nut 2clockwise with a screwdriver. The
set pressure of the relief valve will increase.
CAUTION
• The pressure at which the relief valve operates should be set at about 120% of normal
discharge pressure. Avoid setting at above 120% of the rated maximum pressure of the
pump since this may cause the pump to become overloaded.
IMPORTANT
• In order to set the pressure of the relief valve, furnish the pump discharge side with a
pressure gauge and stop valve (as shown below).
5 Operating Principle
(1) The motor rotation is reduced by the worm.wheel gear (SX models) or the planetary gear
(SY models).
(2) Through the action of the eccentric mechanism, the motor’s rotation is converted into a
reciprocal motion of the pump shaft.
(3) When the diaphragm at the end of the pump shaft moves reciprocally, the volume of pump
head alternately increases and decreases.
This causes the pressure in the pump head to rise and fall alternately, and this pressure
change causes the suction and discharge of chemical.
(4) When the pump shaft moves back, negative pressure occurs in the pump head. At this
moment, the discharge side check ball closes to prevent any of the liquid being transferred
along the discharge side piping from flowing back into the pump head (Fig. 1). On the
other hand, the suction side check ball opens the valve to allow liquid to flow into
the pump head from the suction side.
(5) When the diaphragm moves front, positive pressure occurs in the pump head. The
suction side check ball closes and the discharge side check ball opens to allow the liquid
to be discharged (Fig. 2).

(6) On the double diaphragm type, in addition to the drive diaphragm, a corrugated PTFE
diaphragm is provided at the liquid end. The space between these two diaphragms is
filled with buffer solution (glycerin, purified water or silicone oil), in order to transmit the
reciprocal motions of the drive diaphragm accurately and uniformly to the PTFE
diaphragm (front diaphragm). As a result, the diaphragm’s working life is dramatically
extended.
