A4VSO泵具有泵具有噪音低、體積小、自吸能力好、可靠性高等優(yōu)點(diǎn)。在閉式系統(tǒng)上應(yīng)用,油泵變量過(guò)零位時(shí)一般柱塞泵都有托盤(pán)現(xiàn)象,唯獨(dú)D-A4VSO泵有效解決此類(lèi)問(wèn)題,因補(bǔ)油泵、控制泵可以串接、控制閥可以集成在泵蓋上,其結(jié)構(gòu)非常緊湊;另外,比例泵均帶有位移傳感器閉式反饋回路,其零位控制精度非常高。廣泛應(yīng)用于:冶金行業(yè)、鍛壓行業(yè)、船舶行業(yè)、船舶等等領(lǐng)域。A4VSO系列規(guī)格有40、71、125、180、250:;變量形式有恒壓,恒功率、液動(dòng)、負(fù)載感應(yīng)、比例、伺服、壓力流量復(fù)合控制形式;有開(kāi)式系統(tǒng)泵和閉式系統(tǒng)泵。A10-FR01B-12,A10-FR01C-12,A10-FR01H-12,
