[Example 1] Fuel transportation for emergency power generator in tall buildings

In general, fuel transportation in a tall building requires multiple pumps to relay the fuel. However, a single Daito Kogyo gear pump can pump and transport fuel from an underground tank to the upper floors, so there is no need to install any intermediate tank at middle floors. Our gear pumps thus reduce cost and save space.

[Example 2] Pumping and transporting fluid from an underground tank

Even under the harsh conditions of pumping up fluid from an underground tank, such as a pump head of about -9 m, Daito Kogyo's gear pumps will work reliably. Our gear pumps are also widely used for various purposes including suction from a vacuum tank or suction of highly viscous liquid.

[Example 3] Piping with back pressure from suction side

When there is strong pressure from the suction side or back pressure, the pressure balance within a normal gear pump is vulnerable, causing components to be worn faster. Our double shaft seal pump and seal-less gear pump suffer less wear and are long-lasting even in such piping because a gear controls the balance in the pump.

[Example 4] Gear pumps for high-pressure gas

Our seal-less gear pumps can be designed and manufactured to accommodate various specifications of high-pressure gas.

[Example 5] Planning/installation of independent safety valve

We also manufacture original independent safety valves, which provide protection for piping and pumps. Independent safety valves for transportation lines for highly viscous liquids/high temperature fluids are also available.

■ Applicable to various liquids

[Example 6] Transportation of liquids that harden upon contact with air (e.g. resin/paint)

Resin or paint that hardens upon contact with air adheres to the mechanically sealed parts of a pump, making maintenance difficult. With our seal-less gear pump, pumped liquid can be transported cleanly and efficiently as the pump is completely sealed from air.

[Example 7] Transportation of waste, hazardous or harmful fluids

In case of transporting harmful fluid, hazardous combustible fluid, or waste fluid, our double bellows mechanically sealed or seal-less gear pumps are capable of minimizing or eliminating leakage, ensuring safe transportation.

■ Applicable to various specifications

[Example 8] Transportation of low- to high-temperature/viscous oils, etc.
Even if the temperature/viscosity of a pumped fluid varies widely, in combination with a motor with inverter or speed variator, constant flow rate or flow rate control can be provided.
Installation example:
Viscosity	Min. 10 mPa•s@150°C to Max. 10,000 mPa•s@ -20°C When transportation of the above oil at a constant rate or certain amount is desired, an inverter constant-torque motor in combination with a gear pump controls the rotation speed to 200-600 min^-1, and the inverter varies the rotation speed so that the oil is transported corresponding to changes in temperature and viscosity.

[Example 9] Pumps for apparatus dealing with multiple kinds of fluid

By controlling gear pumps for each kind of fluid by an inverter, multiple kinds of fluid can be mixed at a fixed blend ratio. Our gear pumps accommodate a wide range of flow rate, and depending on the condition, discharge pressure of up to about 7 MPa can be provided.
