As a global leader in shielded pump technology, the core features of HERMETIC's products are "extreme safety concept, unique wear-resistant technology, and wide performance boundaries covering extreme working conditions". These characteristics make it the preferred choice for high-risk and high demand industries such as chemical, nuclear power, LNG, etc.

The following are the core technical features based on official information:

1、 Disruptive structural design: integration and zero leakage
This is the cornerstone of all the advantages of the Haimitick shielded pump.

Completely unsealed structure: Integrating the motor and pump body into a closed unit completely eliminates external rotating components, couplings, and the most vulnerable mechanical seals, fundamentally eliminating leakage points. This not only means 100% airtightness, but also eliminates the need for complex sealing aids and barrier fluid systems.

Double safety shell: The pump is equipped with a secondary safety shell. Even in extreme cases where the main shielding sleeve fails, the transported hazardous medium will not immediately leak into the atmosphere, providing additional safety assurance for the factory.

Compact structure and minimalist maintenance: The integrated design makes the pump occupy a very small area. Due to the absence of easily worn-out mechanical seals and couplings, the number of components has been significantly reduced, which not only lowers the failure rate but also makes maintenance work exceptionally simple, resulting in lower lifecycle costs.

2、 Exclusive ZART ®  Wear free technology
This is the exclusive patented technology that Haimitick is most proud of, aimed at achieving "zero contact" operation and fundamentally eliminating wear and tear.

Zero axial and radial thrust: ZART ®  Technology ensures that the rotor is completely suspended and contactless during operation through a series of intricate design details. This eliminates wear caused by bearing contact, so theoretically the equipment can maintain stable performance for decades.

The source of ultimate reliability: Since there is no wear and tear without contact, the mean time between failures (MTBF) of the pump is maximized, and the cost of unexpected downtime and maintenance is minimized. For vertical pumps, Haimitike even provides unique magnetic thrust bearings to ensure contactless operation during start-up and shutdown.

3、 Excellent ability to cope with extreme working conditions
Haimitick pumps are designed for the most demanding applications, with a wide range of performance boundaries:

Technical dimension, capability scope, key design and application
The unique ceramic insulation technology with a maximum temperature range of -160 ° C to+480 ° C enables the motor winding to operate reliably even at medium temperatures up to 400 ° C.
The maximum pressure can reach up to 120 MPa (approximately 1200 bar), and the motor housing and pump body can be designed with the same pressure rating to meet the requirements of ultra-high pressure processes.
The maximum power range of 1 kW to 690 kW provides the largest capacity shielded pump product series on the market.
The integration of high temperature and high pressure adopts a centerline support structure and an independent circulation loop with an external cooler for working conditions above 320 ° C to 450 ° C, achieving thermal coupling between the high temperature medium and the motor, ensuring that the motor operates at the allowable temperature.
4、 Complete state monitoring and intelligent solutions
In order to ensure absolute safety in critical processes, Haimitick integrates advanced condition monitoring functions.

Intelligent monitoring system: The pump can be equipped with a LVDT based rotor position monitoring (MAP system) to monitor the real-time operation status of the rotor.

Customization capability: Haimitike provides ETO (design to order) services, which can provide customized solutions according to customers' special needs, from single units to batches, to meet the requirements of cutting-edge fields such as fourth generation nuclear reactors.

summary
The technical characteristics of the Haimitike shielded pump can be summarized as follows: based on an integrated unsealed structure, with exclusive ZART ® With zero wear technology as the core, we provide safe, reliable, and long-lasting fluid transportation solutions for the world's most demanding industrial challenges through extreme performance boundaries and intelligent monitoring methods.
