Xierke Advantage Supply Kral CKC-370 Screw Pump

Xier Ke Advantageous Supply Kral CKC-370The screw pump works by the meshing rotation of two idler screws and one main screw inside the pump casing. The medium is enclosed in the sealed chamber formed by the screws and smoothly pushes from the suction end to the discharge end in the axial direction.

Xier Ke Advantageous Supply Kral CKC-370Screw pump with stable flow and extremely low pulsation: The three screw meshing design achieves continuous and pulsation free conveying, with flow fluctuations of less than ± 2%, making it particularly suitable for lubrication, hydraulic, and metering systems that require high pressure stability.

Strong self-priming ability and anti cavitation: Optimized suction chamber structure and screw profile, self-priming height can reach 4-6m (depending on the medium), short-term dry operation does not damage the pump body, and start stop is more relaxed.

Efficient and energy-saving, low temperature rise: the volumetric efficiency is usually greater than 92%, and the mechanical transmission loss is small; The medium has low shear force and maintains its physical properties unchanged for high viscosity and thermosensitive fluids.

Low noise, low vibration, long lifespan: The dynamic balance accuracy reaches G2.5 level, and the operating noise is usually less than 75 dB (A). The bearing and sealing system have a long lifespan, greatly reducing the maintenance cost throughout the entire lifecycle.

Wide working condition adaptation: Supports variable frequency speed regulation, linear matching of flow and speed, and maintains stable output even under pressure/temperature fluctuations.

Pump body/end cap: Available in HT250 cast iron, 1.4301 (304), 1.4404 (316L) or duplex stainless steel, with corrosion resistance/pressure resistance levels customized according to the medium.

Screw pair: The master and slave screws are made of 20CrMnTi or 17-4PH stainless steel, which has been carburized, quenched and precision ground. The surface hardness is HRC58~62, and it is wear-resistant and anti bite.

Sealing system: Standard configuration includes single/double end mechanical seals (SiC/SiC, carbon/tungsten carbide), with optional elastomers such as FKM, EPDM, FFKM, etc., meeting the requirements of -30 ℃~+180 ℃ and strong corrosive media.

Bearings and bushings: high-precision sliding/rolling bearings, some models adopt lifelong lubrication design to reduce on-site maintenance frequency.

Advantage summary: The material selection is highly matched with the medium, and the service life of key friction pairs is increased by more than 30%, eliminating cross contamination and early failure.

Kral pumps are used in industrial lubrication systems for centralized oil supply to gearboxes, compressors, turbines, and rolling mills

Hydraulic and power units: machine tool hydraulic station, injection molding machine, wind turbine yaw/pitch system

High viscosity/sensitive medium transportation: heavy oil, asphalt, resin, adhesive, silicone oil, food grade syrup (optional hygiene grade configuration)

Ships and Energy: Marine Oil/Fuel Transfer, Offshore Platform Injection, Chemical Process Pumps

Advantages summary: One pump has multiple functions and strong medium compatibility; No pulsation characteristics protect downstream precision valves and instruments, significantly improving system reliability.

Export grade protection: fumigated wooden crate/steel wood composite pallet+moisture-proof aluminum foil lining+shock-absorbing foam/corner protector, in compliance with ISPM 15 and CE transportation regulations.

Clear identification: external model, weight, center of gravity, lifting point, anti tilt label, and medium compatibility reminder for easy on-site acceptance and lifting.

Complete accessories: Comes with installation bolts, sealing gaskets, factory certificate of conformity, original instructions, and test reports (pressure/flow/leakage).

Advantages summary: Moisture resistant, shock resistant, and corrosion-resistant, ready for installation upon arrival, reducing transportation losses and unboxing disputes.

Before installation: Check the viscosity/temperature/corrosiveness of the medium and confirm the cleanliness of the pipeline; The alignment between the pump shaft and the motor coupling is ≤ 0.05mm.

Start up operation: Pump exhaust is required for operation, and prolonged idling is strictly prohibited; Suggest installing an inlet filter (≥ 100 mesh) and an outlet safety valve.

Daily maintenance: Check mechanical seal leakage and vibration values every 2000 hours; Lubricate the bearings according to the manual cycle; Immediately shut down for troubleshooting of abnormal temperature rise/noise.

Safety regulations: Adhere to LOTO locking tags, grounding and explosion-proof monitoring are required for high temperature/flammable medium working conditions; Confirm environmental compliance before discharging residual liquid.

Advantages summary: simple structure, no vulnerable impellers/valves, and few maintenance points; Xierke provides a Chinese version of the operation guide and remote technical guidance to reduce the risk of misoperation.

Original genuine direct supply: Establish a stable authorization channel with KRAL AUSTRA, and attach the original factory serial number, material certificate, and performance test report for each batch, supporting authenticity verification.

Technical customization support: Provide selection calculation sheets (viscosity/temperature/pressure/NPSH), 3D models, CAD installation drawings, and support for quick sampling of non-standard interfaces/special seals.

Delivery time and inventory: Regular models are available in domestic safety stock, and emergency orders support urgent production scheduling and air freight delivery from European factories to shorten downtime waiting times.

Full life cycle service: providing 12-24 month warranty, direct supply of spare parts such as sealing packages/screw pairs, on-site debugging guidance, and fault diagnosis response.
