Direct mounting flange interchangeability with legacy model NQJ-180E pump assemblies
Thermal winding protection and enhanced hydraulic resistance against gritty sludge

Self-Priming Coolant Pumps NPJ Series

Dry-installed external coolant pumps engineered with robust self-priming capability for machine tool fluid circulation. The design lifts cutting fluid from recessed sumps, lower chip pans, and remote reservoir compartments without requiring manual suction priming.

Motor output ratings span from 60 W to 750 W to match diverse machining applications
Convenient external mounting on machine base plates outside coolant reservoir tanks
Integral suction check valve preventing backflow drainage and prime loss during halts
Unobstructed service access to the hydraulic impeller chamber for rapid cleaning

Multistage High-Pressure Coolant Pumps NQD Series

Multistage vertical immersion pumps built to supply high-pressure coolant directly through tool spindles and internal flushing nozzles. The units excel in deep-hole drilling, high-speed end milling, and precision machining of heat-resistant aerospace alloys.

Multistage hydraulic chamber fabricated from wear-resistant stainless steel alloy
Elevated discharge pressure ensuring chip evacuation through internal tool channels
Three-phase electric motor ratings extending from 750 W up to 3.7 kW heavy frames
High tolerance against abrasive particle wear when coolants pass 50-micron filters

History of Teral Taku plant and MITSUBISHI-TAKU brand lineage

TERAL TAKU Inc. traces its manufacturing roots to March 1970 when Taku Denki was established in Taku City, Saga Prefecture, Japan, to manufacture pump units for Mitsubishi Electric Corporation.

For more than three decades, the factory produced household and industrial pumps under the Mitsubishi brand, including Kegon series water pumps and machine tool coolant circulation units.

In April 2003, the enterprise joined the Teral Group, and in April 2008, the company name was formally updated to TERAL TAKU Inc.

Numerous operating CNC lathes, milling machines, and machining centers continue to feature legacy MITSUBISHI-TAKU nameplates, for which the modern plant provides fully interchangeable replacement pumps.

Design engineering of NQJ series sealless immersion coolant pumps

Machine tool coolant pumps of the NQJ series are vertical monoblock units engineered for continuous delivery of cutting fluid in milling, drilling, and grinding cycles. The fundamental engineering advantage of NQJ pumps is their sealless configuration without mechanical shaft seals.

The lower hydraulic impeller portion is submerged directly inside the machine fluid reservoir, while the electric motor is mounted on the mounting flange above the reservoir cover plate.

Excess fluid drains smoothly through hydrodynamic relief passages back into the sump, preventing mechanical seal wear, eliminating fluid leakage risks, and ensuring dependable operation with metal swarf and abrasive particulate.

Comparison and modernization from NQJ-180E to NQJ-180G models

Units with a rated 180 W motor output represent the primary workhorse across machine tool workshops. The legacy NQJ-180E generation served as standard factory equipment on precision Japanese and international machine tools for years.

The modernized NQJ-180G generation was developed under energy-efficiency standards, featuring an optimized fluid path that delivers higher hydraulic efficiency and reduced motor current draw.

Mounting flange bolt circles, immersion column dimensions, and the Rc 1/2 threaded discharge port on NQJ-180E and NQJ-180G are identical, enabling direct retrofit without modifying tank lids. Motors connect to three-phase 400 V or 200/220 V industrial power lines.

Self-priming NPJ pumps and multistage high-pressure NQD units

Beyond standard immersion pumps, Teral Taku manufactures specialized industrial fluid handling lines designated NPJ and NQD.

The NPJ series features self-priming electric pumps designed for dry mounting outside fluid tanks, pulling cutting fluid from lower machine base sumps through high vacuum suction without pre-filling lines.

The NQD series consists of multistage high-pressure immersion units that deliver elevated discharge pressure for through-spindle cooling and internal tool flushing during deep-hole drilling and high-speed profiling.

Hydraulic stages of NQD pumps are fabricated from wear-resistant stainless steel to resist erosive wear from fine metal chips.

Preventive maintenance protocols and operational diagnostics

Long service life for Teral Taku machine tool pumps is achieved through routine monitoring of cutting emulsion condition and strainer cleanliness.

Pumps handle mineral oils as well as synthetic water-soluble coolants with fluid kinematic viscosity up to 150 mm²/s and fluid temperatures ranging from minus 20 to plus 60 degrees Celsius.

Routine servicing includes inspecting suction intake ports, checking stator winding insulation resistance, and verifying smooth rotation of precision ball bearings.

If unusual vibration or flow reduction is observed, technicians inspect the impeller and volute diffuser for swarf accumulation or mechanical erosion.

Technical selection and component ordering by machine nameplate

For accurate identification of MITSUBISHI-TAKU pump units and factory Teral Taku replacement parts, referencing the factory equipment nameplate is recommended.

The metal nameplate provides the full alphanumeric model designation, immersion column depth, supply voltage (200 V, 220 V, or 400 V), line frequency, and rated power output.

When replacing discontinued legacy series such as NQ-150E or NQ-180J, our engineering team selects the equivalent modernized NQJ-180G model maintaining identical mechanical interfaces.
