Donghua plunger is made of materials that have high levels of hardness and wear-resistant properties. The surface hardness degree can be up to HY1000. Plunger seals are pressure resistant and have a long operating life (4-5 times longer than the original one).

Features of Plunger
1. Both heads can be used; the operating life of the plunger is doubled.
2. It applies a flexible connection and determines its own center. This improves the sealing property and prolongs the service life of the plunger and seal.
3. Driving components adopt forced lubrication and circulating cooling device to suit long-term continuous work. The crankshaft has the following characteristics: smooth running, low noise and strong adaptability. It has a rotating speed that is controlled between 130-160 rpm.
