CENTRIFUGAL PUMP/PLUNGER PUMP
As a famous petroleum equipment supplier, SERVA developsthe technology of not only the equipment but also the plunger pump.
Now SJS can product four type of the plunger pump, which are the mainstream pump in the cementing, fracture, sanding, & acid well service.
SJS pump is a famous pump, which the performance and the quality is in the highest flight in the world and almost same as Hallibur­ton, SPM, GD.
SJS can product 400 sets plunger pump per one year. And most of them is used in overseas.
SJS is a main manufacture base in the world.

3.Design feature
       •A light weight, compact structure pump requiring minimal mounting space.
       •A heavy steel frame for horizontal or vertical positioning.Segmented structure allows the customer to purchase the components necessary for repair.

• Special front and rear friction rings are provided with every new pump. If necessary, the bronze friction ring can be replaced.
• Change of rotation direction may be easily accomplished by simply moving, turning and repositioning the volute, and changing the impeller to match the desired direction of rotation.
• The enclosed impellers can provide larger pressure and higher efficiency. Available in either a clockwise or counterclockwise rotation, the impeller is secured to the shaft by a superior designed locking system.
