Mobile Boarding Bridge Hydraulic Power Pack Hydraulic Power Unit

• Compact-sized and lightweight power packages that use minimal oil delivered from a small tank
• High-performance gear pump installed
• Manifold block can be installed directly on the hydraulic pump as an option, making it easy to configure the hydraulic circuit of your choice by installing a small stack valve
• Full return line filter is standard equipment, enabling longer system life
• Variety of options available including temperature gauge, magnet, level switch, manifold block, and more

• During initial system startup (and startups after long period of storage), pump may have difficulty drawing fluid
• By pre-installing an air bleed valve (ABT-03) or by loosening a fitting in the delivery pipe, air can be bled from the system
• During air bleed of pump and piping, pump should be run at no load

• During startup, if viscosity is higher than proper viscosity (54 mm²/s), system should be warmed up with pressure less than half of maximum working pressure until viscosity falls below 54 mm²/s

• Maximum operating pressures, maximum speeds, and other specifications may differ according to the hydraulic fluid used

• Please use general industrial use anti-wear fluids

• Water glycols may be used with standard type pumps, however maximum operating pressures, maximum speeds, and other specifications will differ from those of mineral oil fluids
• Fluorine seals are used with pumps that operate on phosphate ester fluids (designated with "F3-" suffix), however specifications for maximum operating pressures, maximum speeds, etc., will differ from those of mineral oil fluids

• Please operate pump with viscosity level within 13~54 mm²/s range
• Maximum viscosity allowed is 860 mm²/s (220 mm²/s for V20, V30 Series), but warm up and operation should be done in accordance with the "Warm Up" guidelines
• Fluid temperature should be maintained below 65°C
