Brand reference:73977

KRAL's three-screw pumps, positive displacement flow meters, and fluid handling solutions provide high quality, rapid response, and short delivery times. Pump sets, pump skids, and compact dual-pump stations complete our product range and are typically customized according to customer requirements and specifications. Furthermore, various industry standards can be incorporated, ranging from marine certifications (ABS, Lloyd's Register, DNV, BV, etc.) to oil and gas and power generation standards (API 676, API 614, ASME, etc.). KRAL three-screw pumps are commonly used in ship engine rooms, mechanical lubrication, fuel oil transfer, burner and boiler feed applications, hydraulic applications (HPU), crude oil transportation and pipelines, bitumen, asphalt and heavy oil transfer, as well as in the chemical industry.

German Kral valves Kral models Kral prices
Kral valves use liquid as the working medium to transmit energy and perform control. Hydraulic transmission and pneumatic transmission are collectively referred to as fluid power transmission. This is an emerging technology developed based on the principle of hydrostatic pressure transmission proposed by Pascal in the 17th century, and it is widely used in industrial and agricultural production. Advantages of Kral valves: Hydraulic transmission has many outstanding advantages, so its application is very extensive, such as plastic processing machinery, pressure machinery, and machine tools for general industry; construction machinery, building machinery, agricultural machinery, and automobiles in mobile machinery; steel

German Kral pump Kral model Kral price
Kral pump is a type of pump that uses the rotation of helical blades to lift water axially in a spiral pattern. It consists of a shaft, helical blades, and a housing. During pumping, the pump is placed obliquely in the water so that the inclination angle of the pump's main shaft is less than that of the helical blades, with the lower end of the blades in contact with the water. When the prime mover drives the screw pump shaft to rotate via a variable speed device, water enters the blades, rises along the spiral flow channel, and exits. The structure is simple, easy to manufacture, offers high flow rate, low head loss, and high efficiency, and is easy to maintain. However, it has low head and low rotational speed, requiring a variable speed device. It is mostly used for irrigation.

German Kral coupling Kral model Kral price
Kral couplings contain an elastic compound with pre-compressed rubber, providing additional strength and extending service life. This coupling accommodates all types of misalignment. The hub material is high-strength aluminum alloy, which is both lightweight and corrosion-resistant. The rubber component is primarily used for vibration damping, ensuring smooth and quiet power transmission, thereby protecting the drive source and driven machinery. Installation is simple; since the rubber part is a split insert, it can be installed by insertion after shaft alignment. Elastic couplings use parallel or spiral slit systems to accommodate various misalignments and transmit torque precisely. Elastic coupling

German Kral bearings, Kral models, Kral prices
Kral roller bearings with cylindrical rollers, where the rollers are thin and long relative to their diameter. These rollers are called needle rollers. Despite having a small cross-section, the bearings still have high load-carrying capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D ≤ 5mm, L/D ≥ 2.5, L is the roller length), resulting in a compact radial structure. When the inner diameter and load capacity are the same as other types of bearings, the outer diameter is the smallest, making them particularly suitable for support structures with limited radial installation space. Depending on the application, bearings without inner rings or needle roller and cage assemblies can be selected.

Germany Kral seals Kral models Kral prices
Kral seals are a typical representative of oil seals; the term "oil seal" generally refers to skeleton oil seals. The function of an oil seal is generally to isolate components requiring lubrication in transmission parts from the external environment, preventing lubricating oil leakage. The skeleton acts like reinforcing steel in concrete components, providing reinforcement and enabling the oil seal to maintain its shape and tension. According to structural form, they can be divided into single-lip skeleton oil seals and double-lip skeleton oil seals. The secondary lip of a double-lip skeleton oil seal serves as a dust seal, preventing external dust, impurities, etc., from entering the machine interior. According to skeleton type, they can be divided into inner-covered skeleton oil seals and exposed skel
