TOP-10A Oil Pump – NOP Nippon Trochoid® Oil Pump

Product Name

TOP-10A Oil Pump | NOP Nippon Trochoid® Internal Gear Pump

Model Number

TOP-10A

Brand

NOP – Nippon Oil Pump

Product Category

Oil Pump / Trochoid Pump / Lubrication Pump / Small Internal Gear Pump

Product Details

The NOP TOP-10A Oil Pump is a compact, small-capacity Trochoid® internal gear pump designed for transferring oil, lubricating oil and hydraulic oil in industrial equipment.

The pump uses an internal gear/rotor mechanism in which the inner and outer rotors rotate together to transport fluid. Its compact construction makes it suitable for machinery where a small oil flow and low discharge pressure are required.

According to the manufacturer, the TOP-10A has a theoretical displacement of 0.8 cm³/rev, theoretical discharge of 1.2 L/min at 1500 rpm and 1.4 L/min at 1800 rpm, with a maximum pressure of 0.5 MPa and maximum rotational speed of 3000 rpm.

Description

The TOP-10A Trochoid Oil Pump is part of NOP's small-capacity 1A series. Trochoid pumps are positive-displacement internal gear pumps that provide smooth oil transfer in compact machinery.

The TOP-10A is particularly suitable for lubrication systems, machine tools, industrial machinery and oil circulation applications where a relatively small flow rate is required.

Its compact size and low-pressure design make it an option for equipment requiring continuous lubrication or controlled oil transfer. The manufacturer lists applications including transfer of lubricant and hydraulic oil.
