坚固的铸铁阀体
All Cardinal pumps offer rugged split casing design with heavy-duty class 30 cast iron used for the pump casting, 汽车附件, impellers 和 volutes to provide long life in the field. 
 
Precision-Made Sleeve Bearings
Cardinal offers three bearing types: st和ard sleeve bearing, the Harley™ sleeve bearing by Cardinal, 和 the Harley™ sleeve bearing with TecSonics™ bearing wear monitoring.
 
全面的压力测试
All Cardinal pump 和 motor units are pressure-tested to 50 PSIG to ensure the integrity of the complete unit.
 
Ground Shafts 和 Dynamic Balancing
All Cardinal sleeve bearing pumps have the bearing journals 和 thrust surfaces ground between centers to ensure alignment 和 surface finish. All pump shaft, impeller, 和 motor assemblies are dynamically balanced for long-term operation.
 
电气测试
Motor windings are all tested for 60 seconds at (2 x voltage + 1000) to ensure electrical integrity 和 continuity, with winding resistance taken both before 和 after the pump is built. All Cardinal pumps are meggar tested to ensure the integrity of the insulation.
 
Thermo-Siphon流
Impellers are designed to permit thermo-siphon flow when the pump is not operating, allowing natural convection even when the pump is completely shut off.
 
操作温度
Continuous duty operating temperature ranges from –40ºC (–40ºF) to 100ºC (212ºF).
 
防锈
Special coating is applied to the outside of the pump to protect it from rust. Internal surfaces of the casing can be coated at the customer’s request.
 
高效的汽车
Highly efficient oil-immersed motors are available in single or dual voltage, 单相或三相, 50 or 60 hertz frequencies.
 
铁路服务
Cardinal Pumps can also be specially designed to meet existing pump dimensions 和 performance requirements, including pumps suitable for rail car service.
