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 V-Line: Modular configurable canned motor pumps for the chemical and petrochemical industries

    Thanks to the restructuring of its pump portfolio into three clearly divided areas, HERMETIC-Pumpen GmbH, a leading developer and manufacturer of hermetically sealed pumps, has geared its product range even more consistently to the market dynamics in plant construction. The specialist for canned motor pumps has combined a defined selection of common single-stage and multi-stage chemical pumps in the product are “V-Line” and optimised their production and logistics. The result: V-Line offers modular configurable pump variants with optimised delivery times of 8 to 12 weeks for a wide range of applications. Without exception, all pumps meet the high HERMETIC quality standards including the unique ZART® (Zero Axial and Radial Thrust) principle.
