E-series
An All-in-one, High-to-medium
Pressure Coolant Pump
Vortex unit. No line and suction filters are required. The use of a Vortex unit reduces the required space to about 1/50th by volume of that occupied by a conventional coolant system. The saved space expands the available plant space, resulting in a higher production efficiency.
- Maximum operating pressure: 7.0MPa
- Maximum discharge: 18 liters/min.
- No suction filter is required.
- No line filter is required.
- No clean tank is required.
- No transfer pump is required on the dirty-tank end.
- No plumbing is required to interconnect various components.
*Aqueous solution with 2% or more water-soluble coolant fluid. The water-insoluble coolant fluid of less than 15mm2/s viscosity
Automatic Self-cleaning
Turbulence™ Filter
Our special Turbulence™ design generates turbulence. The combined action of the turbulence and centrifugal force washes away chips from the filter automatically. The result is a maintenance-free unit with a stable high pressure and large flow rate.
*Chips larger than 20μm in size removed (when using aqueous solution containing 2% or more water-soluble coolant fluid).

Two Types of Pump to Choose
You have two options — the powerful plunger pump and the high-efficiency Trochoid™ pump — depending on your application.
- Compatible types of fluid
- Aqueous solution containing 2% or more water-soluble coolant fluid
Water-insoluble coolant fluid of 15mm2/s or less viscosity* - Not for lubricant oil or fuel oil
- Not for clear water, purified water, water solutions without rust-preventive property, viscous fluids, corrosive liquid, solvents, and oils
- *EP is limited to use with water-soluble coolants.
- Aqueous solution containing 2% or more water-soluble coolant fluid
- Relief valve is built into the unit

Huge Energy Saving Effect
Reduces Utility Costs*
The use of a Vortex results in huge energy savings over the conventional centrifugal pumps. The electric power cost is greatly reduced.
- Operating cycle: Unload: 20 sec. → Drill 1 Center Through: 20 sec. → Unload: 20 sec. → Drill 2 Center Through: 20 sec.
- Center Through pressure: 1.1MPa
- *Calculated on the basis of operating time 8h/day, operating days 365/year, and the electric power cost ¥20/kWh.
