High pressure gear pump KP 5

Product catalog summary
Overview: The KP 5 series high-pressure gear pumps by KRACHT GmbH are designed for use in oil-hydraulic plants, suitable for hydraulic fluids and mineral oil bases. They are constructed with high-grade cast iron housing and hardened steel shafts and gears.
Specifications: The pumps can handle external radial forces and have a direction of rotation that affects the conveyance direction. They operate within an ambient temperature range of -20°C to +60°C and a fluid temperature range of -20°C to +120°C, depending on the shaft seal material. The operating pressure ranges from -0.4 bar to 2.0 bar at the inlet and up to specified maximums at the outlet.
Construction: Key components include multi-layer bearings for the shafts, NBR or FKM shaft seals, and an outboard bearing for radial and axial forces. The use of fine-meshed filters is recommended to extend service life.
Technical Information: The pumps feature a flange type fixing, optional mounting positions, and can rotate clockwise or anticlockwise. They have specific discharge flow rates and input power requirements, which vary with pressure and viscosity.
Performance Parameters: The document provides formulas for calculating discharge flow, drive torque, and input power. It also includes efficiency values for volumetric and total efficiency.
Displacement and Power: The pumps are available in nominal sizes with specific displacement, speed range, and torque values. The discharge flow and required input power are detailed for various pressures and speeds.
Type Key and Ordering: The document includes a type key for ordering, specifying seals, gearing, materials, shaft ends, and other configurations.
Dimensions and Connections: Detailed dimensions for flange types and shaft ends are provided, along with connection specifications for inlet and outlet ports.
Accessories: Information on couplings, including materials, sizes, and ordering codes, is included. The document also specifies motor and pump combinations, with details on power, speed, and coupling types.
Product Portfolio: KRACHT GmbH offers a range of products including valves, hydraulics, flow measurement devices, and gear pumps for various applications.
