KQZ2500輕型五缸柱塞泵是一種往復式、容積式、臥式單作用五缸柱塞泵，其最大輸入功率1866kW(2500hp),沖程203.2mm（8〞），柱塞直徑可以在3 1/2〞-5 1/2〞之間選擇，以滿足用戶對不同壓力和排量的要求。所有不同直徑柱塞的液力端所配的動力端是相同的。該泵用于間斷性油井作業，如酸化、壓裂和壓井等。

    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.

與市場上同功率的柱塞泵相比，該2500泵具有以下優點：

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

1、該型號柱塞泵具有壓力高、排量大的特點，在近幾年石油壓裂市場得到廣泛的推廣應用，是經過市場檢驗的成熟產品，成為目前大功率壓裂的首選產品；

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、獨特的密封結構設計，保證整機運行更加可靠；

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

3、采用人字齒輪減速機構，傳動平穩可靠，能夠有效的保證整泵在低噪音、高效率的情況下持續較長時間運行；

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、體積較小、重量輕，更適合用于車載設備，在提供大排量和高壓力的同時，便于維修和操作；

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;
