Trochoid Pump

This pump that transfers oil using an internal gear mechanism where an external and an internal gear mesh and rotate together. It is used across various fields, such as transferring cooling and lubricating oil in machine tools, as well as in ships and agricultural machinery. NOP's Trochoid® pump minimizes gear meshing irregularities to the utmost extent, earning high acclaim for its quality and maintaining a market share of approximately 70% in Japan's machine tool industry.

Orbmark motor

The NOP original internal gear-type hydraulic motor features a fully lubricated design, with all essential operating components completely immersed in circulating hydraulic fluid. This design ensures a long service life and cost-effective operation. We offer a wide range of models tailored to various specifications and operating environments, along with a comprehensive selection of accessories, including gear reducers and valves.

Procom Pump (water pump)

The Procon Pump is a self-priming pump that transfers water using rotating vanes (blades). Capable of discharging at high pressure, it eliminates metal-to-metal contact by incorporating low-friction carbon graphite in sliding components such as the vanes. This design ensures superior quietness and durability. The pump is widely used in mechanical industry applications, including cooling systems for welding machines and hydraulic pressure generators, as well as in the food and beverage industry.

Trochoid Pump with suction filter

Among the various Trochoid Pumps from NOP, this particular model, equipped with a suction filter, is especially suited for transferring cutting fluids (water-based or oil-based coolants). It is compact and features a dual W filter design, meaning there is no need to stop the machine for filter replacement, ensuring high productivity. Additionally, the pump operates with low noise and boasts a long lifespan—key benefits highly appreciated by users.

Indexing motor

The standard "EIS series" hydraulic rotary positioning motor features a hydraulic system that delivers high torque, high-speed indexing, and space-saving performance. Positioning is achieved through deceleration via a built-in mechanical valve, ensuring reduced shock and smooth indexing as key benefits.

Coolant tank (coolant unit)

Coolant unit with chip conveyor, equipped with an NOP cyclone filter pump. Developed in collaboration with Suzuka IP (Thailand), this coolant unit is tailored for the Thai market and designed for BT30-type machining centers. The NOP cyclone filter pump effectively removes sludge, eliminating the need for a drum filter and resulting in a maintenance-free coolant unit with fewer breakdowns. Additionally, we offer consultations for modifications and improvements to existing tanks.
