 KQZ2500轻型五缸柱塞泵是一种往复式、容积式、卧式单作用五缸柱塞泵，其最大输入功率1866kW(2500hp),冲程203.2mm（8〞），柱塞直径可以在3 1/2〞-5 1/2〞之间选择，以满足用户对不同压力和排量的要求。所有不同直径柱塞的液力端所配的动力端是相同的。该泵用于间断性油井作业，如酸化、压裂和压井等。

    KQZ2500 Pump is a reciprocating, volumetric, single acting and horizontal five-cylinder plunger pump, with a maximum input power of 1866KW (2500HP) and stroke of 203.2mm (8"). The The plunger diameter can be selected between 3 1/2" and 5 1/2".To meet users' demands for different pressure and displacement. All fluid ends of different diameter plungers match with the same Power end.The pump is used for intermittent oil well operations, such as acidification, fracturing and pressure well.

与市场上同功率的柱塞泵相比，该2500泵具有以下优点：

Compared with same power plunger pump in the market, the 2500 pump has the following advantages:

1、该型号柱塞泵具有压力高、排量大的特点，在近几年石油压裂市场得到广泛的推广应用，是经过市场检验的成熟产品，成为目前大功率压裂的首选产品；

1, It has the characteristics of high pressure, large displacement, and it has been widely applied in fracturing performance of oil market in recent years, which is a mature product through market survey, and the first choice of the current large power fracturing products;

2、独特的密封结构设计，保证整机运行更加可靠；

2, Unique sealing structure design which guarantee the machine running more reliable;

3、采用人字齿轮减速机构，传动平稳可靠，能够有效的保证整泵在低噪音、高效率的情况下持续较长时间运行；

3, Using the herringbone gear retarding mechanism, which is stable and reliable, and can effectively ensure the pump perform in low noise and high efficiency for a long time;

4、体积较小、重量轻，更适合用于车载设备，在提供大排量和高压力的同时，便于维修和操作；

4, In small volume, light weight, it is more suitable for on-board equipment, while provide large displacement and high pressure, which is easy for maintenance and operation;
