Our cold extrusion motor bodies can endure pressures above 30Mpa. High strength cast iron front & rear covers also enhance our reliability. Our units are widely used in the industrial, mobile, marine and aerospace industries. CHARACTERISTICS Vincke gear pumps are produced in 5 different...

your Hydraulic Brand FILTER RECOMMENDATION • By far largest number of premature failures of gear pumps is due to contamination; filtering with clogging indicating and alarms are recommended. • The initial contamination of the fluid must not exceed class 10 NAS 1638,pass experience has shown that even brand new fluid often exceed this value in this case it is recommended below: 60µm inlet , and in the return side: Standard PRESSURE DEFINITION INLET PRESSURE P3= peak max. pressure P2= intermittent max. pressure P1= continuous max. pressure Under standard working conditions, intake pipe pressure...

your Hydraulic Brand DESIGN CALCULATIONS FOR PUMP Q= flow rote (l/m) M = torque P = power N = speed r/min A = inside area of pipe (cm2) v = Q / 6 • A (m/s) V= displacement [cm3/rotation] n = rota/ion speed [rotations per minute] ηvol = pump volumetric efficiency, take 0.95 as an indicative value for rotation speeds ranging between 1.000 and 2000 rpm. ΔP = pressure differential (bar) ηhm = hydromechanical efficiency, take 0.80 as indicative value under cold conditions and 0.85 under working conditions. ηtot = total pump efficiency (ηhm • ηvol) Fluid velocity Calculate the velocity (v) of a fluid...

VNK MULTIPLE GEAR PUMP your Hydraulic Brand MULTIPLE PUMPS The VNKBM pumps can be easily transformed in multiple units. All drive shafts are pre-arranged and have a splined end according DIN 5480. The first unit must always be the same size or bigger than following units. The features and performances are the same of the corresponding single units: only in the case of simultaneous operating you have to verify that the inlet torque is lower than the max. transmissible by the drive shaft. Finally to assembly the multiple pump you need to order bolts of the right lenght. Standard Version W S- two...
