Oil Pumping Engine 

Oil Pumping Unit Model Kit - Build Your Own - Full Metal Model

A pumping unit is the mechanism that converts the rotary movement into a reciprocating vertical movement. Most types of pumping units still in use today are used for crude oil (petrol) extraction. Commonly known as "kowtow machines", they use pressure to get the oil out of the well.

Precision casting and ingenuity. Every time assembly is an industrial reproduction.

As are all our toys, this model is made of metal material, CNC process precision casting and aluminum alloys, oxidized in color.

The mechanical structure of the model is clearly presented, to show the transmission process is visible at a glance. Showing the beauty of the logic, engineering and the powerful machinery at work.

The design presents the core principles of machine operation, and intuitively shows the value of the machine in its application.

The 219 parts are all exquisitely polished by special abrasive tooling techniques, which interprets the wisdom and yearning of human beings in the era of big industry.

You need to assemble the parts step by step, as the whole process is close to professional assembly line craftsmanship, which is interesting and full of experience. This is one of our entry level kids which makes it perfect for our younger audience to learn and get hands on engineering experience.
