臺灣安頌ANSON液壓油泵既有效率，高壓下穩(wěn)定旋轉(zhuǎn)，反應(yīng)靈敏，精度高，流量穩(wěn)定，可以減少馬力的流失等等特點。葉片泵多式多樣，有單聯(lián)泵，雙聯(lián)泵，單聯(lián)和雙聯(lián)的又分開加長和標準的。油泵用到整機上后，噪音不大，可以達到比較理想的寧靜的工作環(huán)境。
1、變量葉片泵PVF高效率，高壓下穩(wěn)定旋轉(zhuǎn)。特殊壓力控制機構(gòu)，凸輪環(huán)3點支撐方式，使在大幅提高時的旋轉(zhuǎn)性能，在140bar下亦可發(fā)揮高效率，穩(wěn)定的性能。
2、變量葉片泵PVF高效率，高壓下穩(wěn)定旋轉(zhuǎn)。采用數(shù)種隔音，防振的新機構(gòu)，尤其可提高凸輪環(huán)旋轉(zhuǎn)的穩(wěn)定性。由控制活塞，偏位活塞所形成的特殊3點支撐方式，減少凸輪環(huán)振動，旋轉(zhuǎn)時務(wù)噪音。
3、變量葉片泵PVF反應(yīng)靈敏，精度夠。嶄新的凸輪環(huán)控制機構(gòu)，凸輪環(huán)無過位移，而提高反應(yīng)靈敏度。啟動，停止，負荷變動時不會改變精密度。
4、變量葉片泵PVF靈敏的特性，流量穩(wěn)定。嶄新的壓力平衡式壓力控制機構(gòu)，在高壓狀態(tài)下流量亦高度的穩(wěn)定順暢。
5、變量葉片泵PVF高效率旋轉(zhuǎn)，減少馬力損失。采用新機構(gòu)減少損失馬力，尤其是高壓無輸出狀態(tài)時，更明顯的減少馬力損失。
6、變量葉片泵PVF維護，檢修容易。壓力調(diào)整裝置和流量調(diào)整裝置放在同一側(cè)面，方便維護，調(diào)整。
