Eternal Hydraulic Hyva Type Dump Gear Pump (EHY/CYB)
Hyva Dump Gear Pump, there are manufactured and available in several options of truck dump pumps. For tipping and less demanding applications we offers a wide range of gear pumps. For high pressure and long continuous operation, we strongly recommends a high performance and high efficiency piston pump. Bent axis design assures slim external dimensions and low noise level operation. Our pumps are subjected to rigorous endurance tests during the product development phase in our laboratory and field testing to simulate 100,000 tipping cycles. This ensures the superior performance and endurance our customers demand. Bearings are able to withstand peak radial and thrust loads to ensure minimum downtime and long lifetime in every application.
Our company all use needle roller bearing gear pumps. The comparisonwith oil-free bearing gear pumps is as follows:
(1) Double row needle roller bearing gear pump:
Advantages: 1. lts bearing capacity is greatly enhanced, and its servicelife is increased by 30%; 2. The requirements for the cleanliness ofhydraulic oil are low, and the anti-pollution ability is strong.Disadvantages: The cost is higher than that of low oil bearings.
(2) Oi-free bearing gear pump:
Advantages: 1. The cost is lower than that of needle roller bearings;2. The noise is relatively small.Disadvantages: 1. High requirements for hydraulic oil cleanliness andlow anti-pollution ability: 2. The service life is lower than that of doublerow needle roller bearings;
