液压泵在冲击和振动的影响下，可能发生断流使用范围包括矿山、冶金、煤矿、石油、化工、交通、船舶、航空、航天、军工、建筑、建材等行业领域的输送液压泵体内壁与泵壳之间有一圈密封圈其优点是：耐磨性好；摩擦系数小；无泄漏；耐高温；无腐蚀；运转平稳安静。
结构简单；密封性好；摩擦系数小；泵轴承受径向力小耐磨性好；使用寿命长；材料耐高温；耐低温；不需要介质长期保存；运行成本低；可承受较大振动强度（一般为5~10kN/mm)且可拆卸方便维修和更换；压力波动小。
密封性好；不发生泄漏可直接对泵进行保护和维修等性能要求.适用于高温工业；对重载及振动条件比较敏感的行业；适用于高粘度流体输送介质；用于输送液体中不能工作液体其工作条件要求有比较高的稳定性和抗冲击性可承受较大压力范围并可应用于高温、高压及高速工况工作环境；且无泄漏出现。
并且采用了独特结构设计使得润滑及热变形减小，使轴承承载能力大了2倍以上，寿命延长了50%以上在泵轴周围装有一个轴承以保持轴向间隙和径向间隙，以避免轴承发热和轴磨损等问题.同时还有较高的噪声和振动因此泵被广泛用于各种类型和不同工作介质和温度条件下所得到应用.其中以油泵作为一个典型产品受到广泛欢迎.但是液压齿轮泵在长期使用后往往会出现磨损、结垢和严重腐蚀现象！尤其是在长期不使用中会出现磨损情况而产生大量污垢导致电机故障或者烧毁泵体严重损坏无法正常工作！因此要避免油泥对水泵内部造成危害以及不能完全排除故障后还继续使用造成新设备损坏造成损失!??)。
使用寿命长了还得重新维护保养维修!??所以为了防止泄漏，安装液压泵前要认真对内部进行清洁检修 90-L-180-KP-5-BC-80-T-C-C8-J-03-FAC-35-35-24 90L180KP5BC80TCC8J03FAC353524 90L180-KP-5-BC-80-T-C-F1-H-03-FAC-21-21-24 90L180KP5BC80TCF1H03FAC212124 90-L-180-KP-5-BC-80-T-C-F1-H-03-FAC-21-21-24 90L180KP5BC80TCF1H03FAC212124 90L180-KP-5-BC-80-T-C-F1-H-03-FAC-45-45-24 90L180KP5BC80TCF1H03FAC454524 90-L-180-KP-5-BC-80-T-C-F1-H-03-FAC-45-45-24 90L180KP5BC80TCF1H03FAC454524 90L180-KP-5-BC-80-T-M-F1-J-03-FAC-32-32-24 90L180KP5BC80TMF1J03FAC323224 90-L-180-KP-5-BC-80-T-M-F1-J-03-FAC-32-32-24 90L180KP5BC80TMF1J03FAC323224 90L180-KP-5-CD-80-S-C-C8-J-03-FAC-42-42-24 90L180KP5CD80SCC8J03FAC424224 90-L-180-KP-5-CD-80-S-C-C8-J-03-FAC-42-42-24 90L180KP5CD80SCC8J03FAC424224 90L180-KP-5-CD-80-S-C-C8-J-09-FAC-35-35-24 90L180KP5CD80SCC8J09FAC353524 90-L-180-KP-5-CD-80-S-C-C8-J-09-FAC-35-35-24 90L180KP5CD80SCC8J09FAC353524 90L180-KP-5-CD-80-S-C-F1-H-03-FAC-42-42-24 90L180KP5CD80SCF1H03FAC424224 90-L-180-KP-5-CD-80-S-C-F1-H-03-FAC-42-42-24 90L180KP5CD80SCF1H03FAC424224 90L180-KP-5-CD-80-S-M-F1-J-03-FAC-32-32-24 90L180KP5CD80SMF1J03FAC323224 90-L-180-KP-5-CD-80-S-M-F1-J-03-FAC-32-32-24 90L180KP5CD80SMF1J03FAC323224 90L180-KP-5-CD-80-T-C-C8-J-03-FAC-35-35-24 90L180KP5CD80TCC8J03FAC353524 90-L-180-KP-5-CD-80-T-C-C8-J-03-FAC-35-35-24 90L180KP5CD80TCC8J03FAC353524 90L180-KP-5-CD-80-T-C-C8-J-05-FAC-32-32-30 90L180KP5CD80TCC8J05FAC323230 90-L-180-KP-5-CD-80-T-C-C8-J-05-FAC-32-32-30 90L180KP5CD80TCC8J05FAC323230 90L180-KP-5-CD-80-T-C-C8-J-05-FAC-42-42-24 90L180KP5CD80TCC8J05FAC424224 90-L-180-KP-5-CD-80-T-C-C8-J-05-FAC-42-42-24 90L180KP5CD80TCC8J05FAC424224 90L180-KP-5-CD-80-T-C-F1-H-03-FAC-45-45-24 90L180KP5CD80TCF1H03FAC454524 90-L-180-KP-5-CD-80-T-C-F1-H-03-FAC-45-45-24 90L180KP5CD80TCF1H03FAC454524 90L180-KP-5-CD-80-T-C-F1-H-05-FAC-20-38-24 90L180KP5CD80TCF1H05FAC203824 90-L-180-KP-5-CD-80-T-C-F1-H-05-FAC-20-38-24 90L180KP5CD80TCF1H05FAC203824 90-L-180-KP-5-CD-80-T-C-F1-J-03-FAC-23-23-28 90L180KP5CD80TCF1J03FAC232328 90L180-KP-5-CD-80-T-M-C8-H-03-FAC-38-38-24 90L180KP5CD80TMC8H03FAC383824 90-L-180-KP-5-CD-80-T-M-C8-H-03-FAC-38-38-24 90L180KP5CD80TMC8H03FAC383824 90L180-KP-5-CD-80-T-M-C8-H-06-FAC-38-38-24 90L180KP5CD80TMC8H06FAC383824 90-L-180-KP-5-CD-80-T-M-C8-H-06-FAC-38-38-24 90L180KP5CD80TMC8H06FAC383824 90L180-KP-5-CD-80-T-M-C8-J-00-EBA-42-42-24 90L180KP5CD80TMC8J00EBA424224 90-L-180-KP-5-CD-80-T-M-C8-J-00-EBA-42-42-24 90L180KP5CD80TMC8J00EBA424224 90L180-KP-5-CD-80-T-M-C8-J-03-FAC-32-32-24 90L180KP5CD80TMC8J03FAC323224 90-L-180-KP-5-CD-80-T-M-C8-J-03-FAC-32-32-24 90L180KP5CD80TMC8J03FAC323224 90L180-KP-5-CD-80-T-M-C8-J-06-FAC-32-32-24 90L180KP5CD80TMC8J06FAC323224 90-L-180-KP-5-CD-80-T-M-C8-J-06-FAC-32-32-24 90L180KP5CD80TMC8J06FAC323224 90L180-KP-5-CD-80-T-M-F1-H-03-FAC-35-35-24 90L180KP5CD80TMF1H03FAC353524 90-L-180-KP-5-CD-80-T-M-F1-H-03-FAC-35-35-24 90L180KP5CD80TMF1H03FAC353524 90L180-KP-5-CD-80-T-M-F1-J-00-EBA-42-42-24 90L180KP5CD80TMF1J00EBA424224 90-L-180-KP-5-CD-80-T-M-F1-J-00-EBA-42-42-24 90L180KP5CD80TMF1J00EBA424224 90L180-KP-5-CD-80-T-M-F1-J-03-FAC-26-26-24 90L180KP5CD80TMF1J03FAC262624 90-L-180-KP-5-CD-80-T-M-F1-J-03-FAC-26-26-24 90L180KP5CD80TMF1J03FAC262624 90L180-KP-5-DE-80-S-C-C8-H-03-FAC-32-32-24 90L180KP5DE80SCC8H03FAC323224 90-L-180-KP-5-DE-80-S-C-C8-H-03-FAC-32-32-24 90L180KP5DE80SCC8H03FAC323224 90L180-KP-5-DE-80-T-C-C8-H-03-FAC-36-36-24 90L180KP5DE80TCC8H03FAC363624 90-L-180-KP-5-DE-80-T-C-C8-H-03-FAC-36-36-24 90L180KP5DE80TCC8H03FAC363624 90L180-KP-5-EF-80-T-C-C8-J-03-FAC-35-35-24 90L180KP5EF80TCC8J03FAC353524 90-L-180-KP-5-EF-80-T-C-C8-J-03-FAC-35-35-24 90L180KP5EF80TCC8J03FAC353524 90L180-KP-5-NN-80-S-C-F1-J-03-FAC-21-21-24 90L180KP5NN80SCF1J03FAC212124 90-L-180-KP-5-NN-80-S-C-F1-J-03-FAC-21-21-24 90L180KP5NN80SCF1J03FAC212124 90L180-KP-5-NN-80-S-M-F1-J-03-FAC-32-32-24 90L180KP5NN80SMF1J03FAC323224 90-L-180-KP-5-NN-80-S-M-F1-J-03-FAC-32-32-24 90L180KP5NN80SMF1J03FAC323224 90L180-KP-5-NN-80-T-C-F1-H-03-EBA-42-42-24 90L180KP5NN80TCF1H03EBA424224 90-L-180-KP-5-NN-80-T-C-F1-H-03-EBA-42-42-24 90L180KP5NN80TCF1H03EBA424224 90L180-KP-5-NN-80-T-C-F1-H-03-FAC-35-35-24 90L180KP5NN80TCF1H03FAC353524 90-L-180-KP-5-NN-80-T-C-F1-H-03-FAC-35-35-24 90L180KP5NN80TCF1H03FAC353524 90L180-KP-5-NN-80-T-C-F1-J-03-FAC-42-42-24 90L180KP5NN80TCF1J03FAC424224 90-L-180-KP-5-NN-80-T-C-F1-J-03-FAC-42-42-24 90L180KP5NN80TCF1J03FAC424224 90L180-KP-5-NN-80-T-M-C8-J-03-NNN-42-42-24 90L180KP5NN80TMC8J03NNN424224 90-L-180-KP-5-NN-80-T-M-C8-J-03-NNN-42-42-24 90L180KP5NN80TMC8J03NNN424224 90L180-KP-5-NN-80-T-M-F1-H-00-FAC-23-23-24 90L180KP5NN80TMF1H00FAC232324 90-L-180-KP-5-NN-80-T-M-F1-H-00-FAC-23-23-24 90L180KP5NN80TMF1H00FAC232324 90L180-KP-5-NN-80-T-M-F1-J-03-NNN-38-38-24 90L180KP5NN80TMF1J03NNN383824 90-L-180-KP-5-NN-80-T-M-F1-J-03-NNN-38-38-24 90L180KP5NN80TMF1J03NNN383824 90L180-KP-5-NN-80-T-M-F1-J-05-FAC-35-35-24 90L180KP5NN80TMF1J05FAC353524 90-L-180-KP-5-NN-80-T-M-F1-J-05-FAC-35-35-24 90L180KP5NN80TMF1J05FAC353524。
