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
Technical Data
Operation and Maintenance Guidelines
Air Bleed
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
Warm Up
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
Hydraulic Fluids
Maximum operating pressures, maximum speeds, and other specifications may differ according to the hydraulic fluid used
Mineral Oils
Please use general industrial use anti-wear fluids
Fire Resistant 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. Please refer to specifications of each pump for details
Fluorine seals are used with pumps that operate on phosphate ester fluids. An "F3-" suffix is used to designate such pumps. However specifications for maximum operating pressures, maximum speeds, etc., will differ from those of mineral oil fluids
Hydraulic Fluid Viscosity and Temperature
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 paragraph on "Warm Up"
