Centrifugal pump is the use of centrifugal impeller rotation of water to generate centrifugal motion to work. Because of its compact structure, a wide range of flow head, smooth operation, easy installation and maintenance features, has been widely used in production and transportation of transport water. However, users often use centrifugal pump irrigation water is often not the case, then what are the correct methods, Xiao Bian below for you to interpret. Centrifugal pump irrigation has wonderful coup Centrifugal pump irrigation water in the following four ways, as follows: 1. Downstream filling method Tap water filling method in many occasions using this method, it just make the pump position below suction Liquid pool (tank) level, the so-called perfusion. Because of this installation has been stored in the pump liquid, so do not need to be opened when the pump filling. In addition, to be installed in the use of the valve for pump maintenance. 2. Tap water filling method for the water quality is not demanding centrifugal pump, or tap water pump feed medium has little effect on other feed pump, tap water can be used, very convenient. 3. Suction sucking method This method is mainly the use of suction equipment to pump the suction pump and the air inside the suction, the liquid sucked up. Extraction equipment available hand press and motorized vacuum pump (often water ring vacuum pump), vacuum pump suction port is really good at the highest part of the pump or drain to pump all the gas. 4. Backfill filling method Backfill filling system uses the discharge side of the high tank for storage back to the filling, using this method, the first start using artificial quasi-pump Caixing. Above is the introduction of the basic method of centrifugal pump irrigation water introduction, I hope for your product use and understanding to provide some help.

Gear Pumps
Gear Pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications.
Gear pumps are also widely used in chemical installations to pump high viscosity fluids. There are two main variations; external gear pumps which use two external spur gears, and internal gear pumps which use an external and an internal spur gears (internal spur gear teeth face inwards, see below). Gear pumps are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution. Some gear pumps are designed to function as either a motor or a pump.
Features:
l Only two moving parts
l Only one stuffing box
l Non-pulsating discharge
l Excellent for high-viscosity liquids
l Constant and even discharge regardless of pressure conditions
l Operates well in either direction
l Can be made to operate with one direction of flow with either rotation
l Low NPSH required
l Single adjustable end clearance
l Easy to maintain
l Flexible design offers application customization
