Rated speed of double pump is governed by pump with lower speed rating. If deliveries of both pumps are combined, rated pressure is governed by pump with lower pressure rating. E ciency Depending on displacement, speed and pressure, volumetric e ciency is 81-98% and overall e ciency is 71-92% with SAE 10W oil at 49°C (120°F). Inlet conditions Pressure on the inlet should not exceed 1 bar (15 psi). Under continuous operation, inlet vacuum should not exceed 0.17 bar (5” Hg). Operating temperatures Under continuous operation, a maximum of 96°C (205°F) is recommended. The maximum temperature for cyclic or intermittent operation is 107°C (225°F). Fluids and ltration For applications requiring re resistant uids, water glycols, water in-oil emulsions and synthetics can be used at slightly reduced ratings. Fluid should be selected with an operating viscosity similar to the petroleum oil described above. For application assistance, consult your Concentric representative. The system should be ltered to provide an ISO code (proposed) cleanliness level of 19/16. A 10 micron lter sized to accommodate full system return line ow, is recommended for most operating environments. Severe conditions may require greater e ciency from the lter. quality products for mechanical & fluid power ~ jbj Techniques Limited, www.jbj.co.uk UK distributor for Concentric Hydraulics
