?液壓泵在沖擊和振動的影響下，可能發生斷流使用范圍包括礦山、冶金、煤礦、石油、化工、交通、船舶、航空、航天、軍工、建筑、建材等行業領域的輸送液壓泵體內壁與泵殼之間有一圈密封圈其優點是：耐磨性好；摩擦系數小；無泄漏；耐高溫；無腐蝕；運轉平穩安靜。
結構簡單；密封性好；摩擦系數小；泵軸承受徑向力小耐磨性好；使用壽命長；材料耐高溫；耐低溫；不需要介質長期保存；運行成本低；可承受較大振動強度（一般為5~10kN/mm)且可拆卸方便維修和更換；壓力波動小。
密封性好；不發生泄漏可直接對泵進行保護和維修等性能要求.適用于高溫工業；對重載及振動條件比較敏感的行業；適用于高粘度流體輸送介質；用于輸送液體中不能工作液體其工作條件要求有比較高的穩定性和抗沖擊性可承受較大壓力范圍并可應用于高溫、高壓及高速工況工作環境；且無泄漏出現。
并且采用了獨特結構設計使得潤滑及熱變形減小，使軸承承載能力大了2倍以上，壽命延長了50%以上在泵軸周圍裝有一個軸承以保持軸向間隙和徑向間隙，以避免軸承發熱和軸磨損等問題.同時還有較高的噪聲和振動因此泵被廣泛用于各種類型和不同工作介質和溫度條件下所得到應用.其中以油泵作為一個典型產品受到廣泛歡迎.但是液壓齒輪泵在長期使用后往往會出現磨損、結垢和嚴重腐蝕現象！尤其是在長期不使用中會出現磨損情況而產生大量污垢導致電機故障或者燒毀泵體嚴重損壞無法正常工作！因此要避免油泥對水泵內部造成危害以及不能完全排除故障后還繼續使用造成新設備損壞造成損失!??)。
使用壽命長了還得重新維護保養維修!??所以為了防止泄漏，安裝液壓泵前要認真對內部進行清潔檢修 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。
