Product series overview
CASAPPA’s KP series gear pumps are known for their high volumetric efficiency and reliability under high working pressure.The component design of this series of pumps has been fully considered to ensure continuous operation under harsh working conditions.
Model analysis and characteristics
The two models you mentioned belong to the KP20 series, but the specific suffixes represent different displacement or configurations.：
KP20.31.5: “In this model.31.5″ usually means that its precise displacement is 31.5 cc/rev (cubic centimeters per revolution).
KP20.4: “In this model.4″ means that its precise displacement is 4 cc/Rev.
Comparison of core parameters
In order to show the differences more clearly, the following is a comparison of the key parameters of the two models：
Parameter KP20.31.5 KP20.4
Displacement 31.5 cc/rev 4 cc/rev
Maximum working pressure 250 bar (25 MPa) 250 bar (25 MPa)
Typical applications require high-pressure systems with medium displacement and precision or low-pressure systems with small displacement.
Application scenario
KP20.31.5: Suitable for hydraulic systems that require higher flow and pressure, such as certain heavy machinery or large hydraulic stations.
KP20.4: It is more suitable for occasions where the flow requirements are not high, but precise control is required, such as some small machinery or lubrication systems.
Purchase and selection suggestions
In the selection of models, in addition to the displacement, factors such as working pressure, speed, sealing material (such as NBR or FKM), and installation method (such as flange type) need to be considered according to the actual system requirements.It is recommended to obtain the most accurate product manuals and technical support through CASAPPA’s official channels or authorized distributors.
