HERMETIC – Sealless Technology Unlimited

HERMETIC-Pumpen GmbH is a leading developer and manufacturer of hermetically sealed pumps and pumping technologies. The specialist for canned motor pumps has earned a worldwide reputation for its safe and long-lasting pumps, which can be used for the most extreme applications and hazardous conveying media. HERMETIC pumps are suitable for fluid temperatures ranging from –160°C up to +480°C and system pressures up to 120 MPa. With power outputs from 1 kW to 690 kW, HERMETIC offers the largest capacity canned motor pumps on the market.

The pump portfolio for use in the chemical and petrochemical industries is divided into two areas: the completely customer-specific E-Line (Engineered-to-Order line) and the modularly configurable V-Line (Variant line). Both product lines offer the same HERMETIC technology including the unique ZART® principle (axial force compensation) and meet the same HERMETIC quality standards. A software-based expert tool helps you to select the right product with just a few clicks.

HERMETIC V-Line: You select – We produce

The V-Line is designed to provide canned motor pumps for common, pre-defined application areas quickly, and with optimised requirements and prices. It therefore supports modular plant construction in the process industry and makes the highly developed pump technology extremely attractive for many other fields of application, both technologically and economically. Single-stage and multi-stage versions are available in various designs, sizes, motor sizes and materials as well as with corresponding monitoring technology.

HERMETIC-E-Line: You define – We design

If technological requirements are so complex due to extreme areas of application and hazardous conveying media that cannot be covered by V-Line pumps, HERMETIC experts can develop a high-end solution that is perfectly tailored to the defined requirements. Manufactured to the highest performance and quality standards and extensively tested, customers receive their individual canned motor pumps in HERMETIC quality, proven a thousand times over.

HERMETIC employs around 440 people at its headquarters in Germany and has subsidiaries in China and the USA. In conjunction with its worldwide service and contract partner network, HERMETIC offers reliable customer service over the entire life cycle of a plant.

  • Submersible Pumps with Canned Motor

    2 maintenance-free slide bearings + 1 meter shaft = 15 meters immersion depth. The new mathematics of submersible pumps

    Canned motor pump technology provides significant advantages and often constitutes a low-priced alternative to conventionally sealed pumps and magnetically coupled installations with external drive, for example due to the omission of long shafts or complex cooling and lubrication systems for mechanical seals.

    As a replacement to conventional submersible pumps, HERMETIC-Pumpen GmbH supplied two 8-stage, sealless canned motor pumps of the TCAM 30/4+4 series. The distinctive feature of the transformation was the customized adaptation of the pumps to the existing plant and its vessels. The pumps were designed for easy installation in the existing tank (with a diameter of 500 mm). The customer, a Swiss fine chemicals company, thus saves the costly, time-consuming conversion of the existing systems in its production plant.


  • HERMETIC supplies sophisticated canned motor pump for diesel desulphurisation

    HERMETIC-Pumpen GmbH supplied a canned motor pump with a flow rate of 1,000 m³/h and a delivery head of 65 m for a new diesel fuel desulphurisation plant of a Chinese refinery. The high system pressures and temperatures prevailing during the desulphurisation process require the highest safety and reliability of the equipment used. The hermetically sealed HERMETIC pump, extensive measuring and control equipment as well as rigorous tests and inspections not only guarantee the plant operator a safe pump solution with high availability. The decisive factor to the refinery was HERMETIC's expertise and experience with the complex challenges of large industrial oil and gas plants. In addition, the pump specialist with a joint venture provides on-site support to manufacturing plants and service offices in China.
