KRACHT KP Series Internal Gear Pump
Overview
The KRACHT KP Series internal gear pump is a high-pressure hydraulic gear pump family engineered for the toughest oil hydraulic duty in mobile and stationary equipment. Built with hydraulic axial clearance compensation, the KRACHT KP Series delivers a smooth, non-pulsating flow across a displacement range of 1.4 to 300 cm³/rev, withstanding continuous operating pressures up to 300 bar (4,351 psi) and remaining insensitive to the pressure peaks and continuous vibration typical of construction, agricultural, and industrial hydraulic circuits.
As the official authorized partner and exclusive regional representative for KRACHT, Seven Star LLC proudly supplies the KRACHT KP Series gear pump to hydraulic equipment builders, industrial maintenance teams, and mobile equipment operators across the Sultanate of Oman, Muscat, and the wider GCC region. Facilities in Sohar and Salalah specify the KRACHT KP Series when they need a genuine, factory-tested gear pump backed by full manufacturer traceability, and Seven Star LLC ensures every KRACHT KP Series pump shipped locally arrives with authentic documentation and local warranty support.
Operating Principle of the KRACHT KP Series
The KRACHT KP Series operates as an external gear-type pump classified among the gland-type bearing pumps, in which two precision-ground gears — a driving shaft pinion and a driven shaft pinion — mesh inside a close-tolerance housing. As the gears rotate, fluid is trapped in the spaces between the gear teeth and the housing wall and carried from the suction port to the discharge port, where the meshing teeth force the fluid out under pressure. Because flow output is directly proportional to shaft speed and gear displacement, the KRACHT KP Series delivers highly predictable, constant flow that is easily reversed simply by reversing the direction of shaft rotation.
A high tooth count, combined with specially shaped tooth profiles, substantially reduces the type-dependent fluctuation in volumetric flow and the associated pressure pulsation, giving downstream hydraulic components smoother operation and less noise. Hydraulic axial clearance compensation within the gland bearings continuously adjusts to counteract wear and internal leakage as the pump operates under load, sustaining volumetric efficiency over long service intervals even as the unit is subjected to peak pressures and cyclic loading in demanding mobile hydraulic circuits.
Engineering Design of the KRACHT KP Series
The housing and flange mounting cover of the KRACHT KP Series are manufactured from high-strength materials with high dynamic load capability, making the pump insensitive to pressure peaks and continuous vibration in the field. Large-scale PTFE-lead coated plain bronze bearings, mounted on steel backs within the housing and flange cover, carry the finely ground bearing pins of the gearing, while the gear teeth themselves are ground and honed to achieve the manufacturing precision needed for quiet, efficient operation across the pump’s rated pressure range.
Sealing is provided by a single radial lip-type shaft seal suited to general fluid pumping duty, with the fluid temperature range spanning -20°C to +150°C depending on seal material selection. The KRACHT KP Series is available with an integral pressure relief valve for pump and system protection, including TUV-approved safety valve variants, and can be supplied in ATEX-rated configurations or as a motor-pump unit with electric or mechanical drive. Multiple-pump combinations — KP plus KP, or KP plus KP plus KP — allow system designers to combine different pump sizes and stages in a single compact installation footprint for filtration, injection molding, press, and mobile equipment applications.
Key Features
The KRACHT KP Series gear pump combines rugged construction with precise, low-pulsation flow delivery. Core capabilities include:
- Displacement range from 1.4 to 300 cm³/rev covering a wide span of hydraulic equipment sizes.
- Maximum operating pressure of 300 bar (4,351 psi) for demanding high-pressure hydraulic circuits.
- Hydraulic axial clearance compensation that sustains volumetric efficiency as the pump wears in service.
- High tooth count and specially shaped gear profiles that minimize flow fluctuation and pressure pulsation.
- Robust housing and flange cover construction rated for high dynamic loads and continuous vibration.
- Fluid temperature range of -20°C to +150°C depending on shaft seal material selection.
- Optional integral pressure relief valve, including TUV-approved safety valve configurations.
- ATEX version and multiple-pump combination options for specialized and space-constrained installations.
Industrial Applications
Mobile and stationary hydraulic systems throughout the region rely on the KRACHT KP Series wherever consistent, non-pulsating flow is essential to system performance. Construction and agricultural machinery manufacturers specify the KRACHT KP Series for boom, steering, and implement hydraulic circuits, while municipal and special vehicles use it to power auxiliary hydraulic functions under continuous duty cycles. In stationary industrial hydraulics, the KRACHT KP Series drives press machinery, plastic injection systems, and steel hydraulic engineering equipment across process plants in Muscat and the wider Sultanate of Oman, and filtration systems throughout the region’s oil, gas, and desalination infrastructure use the pump’s smooth flow characteristics to maintain consistent filter differential pressure.
As the officially authorized partner for KRACHT, Seven Star LLC distributes the KRACHT KP Series to hydraulic system integrators, OEM equipment manufacturers, and industrial maintenance contractors operating within the Sohar and Salalah economic zones, as well as to industrial clients throughout Muscat and the broader Sultanate of Oman. Because every KRACHT KP Series pump is genuinely sourced through the authorized supply chain, plant engineers and equipment builders can specify it with full confidence in its traceable quality for both new hydraulic system builds and pump replacement programs across the GCC.
