FAQ
Q: The introduction of this model mentions a plunger pump, what is a plunger pump?
A: Plunger pump is an important device of the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder, so that the volume of the sealed working chamber changes to realize the suction and compression of oil. Plunger pumps have the advantages of high rated pressure, compact structure, high efficiency and easy flow adjustment.
Q: What are the advantages of this vehicle compared with 398T?
A: 398T is assembled with Danfoss load-sensitive valve, the price is higher, it is the top match in all products of our company. 398 is assembled with domestic load-sensitive valve, the export volume is more, the price is more acceptable for most customers.
