INDEX Section Modification from former edition. ID02

^ CASAPPA FLUID POWER DESIGN FEATURES Variable displacement axial piston pumps swash plate design ideally suited for medium and high pressure open circuit applications. The compact design allows to be mounted directly on engine motors. TYPICAL APPLICATIONS • Skid Steer Loaders • Wheel Loaders - Backhoe Loaders • Mini and Midi-Excavators • Telehandlers • Forklifts • Windmills - Green Energy • Tractors & Attachements APPLICATION Medium, high pressure SECTOR Mobile 6 Max. displacement limiter 9 Min. displacement limiter 11 Piston guide plate • Compact design • Longer service life •...

^ CASAPPA FLUID POWER DESIGN GENERAL INFORMATION / INSTRUCTIONS Casappa recommends to use its own production filters: DIRECTION OF ROTATION Clockwise or anti-clockwise defined looking at the drive shaft. HYDRAULIC FLUID Mineral oil based hydraulic fluid conforming to DIN 51524, fire resistant fluids and biodegradable fluids according to the technical data shown in the tables on pages 5 ^ 7. The system should be designed to prevent aeration of the hydraulic fluid. FLUID VISCOSITY The fluid viscosity range for optimal use of MVP pump is between 15 and 35 cSt (77 and 163 SSU). Functional limit...

MOUNTING POSITIONS Standard pump is supplied with D1 drain hole open and D2, D3, D4 plugged. Before installation fill the pump with hydraulic oil for at least 3/4 of the volume keeping it in horizontal position. The pump can be mounted in a horizontal or vertical position. The highest of the case drain ports must be used to keep the required filling oil. If D1 is not the highest drain port it must be closed by moving the plug from the hole chosen for the drain line. The pump can be located above the oil level if the absolute pressure at the inlet port stays within the stated limits. With...

DISPLACEMENTS AND WORKING PRESSURES RANGE Pump series PRESSURE DEFINITION p2 Intermittent pressure p3 Peak pressure To ensure proper operation, both p2 and p3 pressures must be kept within the limits stated on page 7 ÷ 9. If p2 is compliant, but p3 exceeds its limit, please decrease the relief setting p2 in order to keep the peak pressure p3 within the limit. For high frequency applications please consult our technical sales department.
