SDR DIN Agitators
The SDR DIN agitators are designed for full compliance with all applicable DIN standards. The advanced modular system integrates easily in any environment. Fast seal replacement by swivelling upper lantern part in one of the outstanding features.
STELZER
Standard DIN Vortex Agitators
The Stelzer standard DIN Vortex agitator revolutionizes agitator field maintenance. Innovatory design allows the lateral removal of the mechanical seal within less than an hour. All vortex agitators are equipped with a standard mechanical seal, shaft and coupling replacement unit for fast lateral disassembly and assembly.
The DIN vortex agitators are fit for use in explosive atmospheres.
STELZER
SNR Standard Agitators
The SNR standard agitator is the typical industrial agitator for medium-sized power and torque requirements. Compact design, quiet operation and a wide range of alternative models are among the characteristics of this product line. The SNR Standard agitators are fit for operation in explosive atmospheres.
STELZER
SSR Side-Entry Agitators
The SSR side-entry agitator was developed as a low-cost alternative for large tank applications. In the SSR side-entry agitator, A large top-entry agitator was replaced by a number of smaller side-entry units. Features of the SSR side-entry agitator include quiet operation, high pumping capacity, an advanced mechanical seal as well as a shut-off device for seal replacement while the tank is filled.
STELZER
SM/SG and SHS/SHK Compact Agitators
Benefits of the SM/SG and the SHS/SHK compact agitators include reliable performance even at low torque, perfect concentricity and quiet operation at all speeds, a wide range of applications even for the standard unit and low-cost system modifications through the use of a great variety of alternate components.
STELZER
hermet Magnetic-Drive Agitators
The hermet magnetic-drive agitators are used in all industries where products must be handled in a sterile environment. The hermet magnetic-drive agitators system is fit for CIP and SIP and materials have been FDA approved for compliance with current GMP. The hygienic design, no-maintenance operation and the hermetic sealing system set new standards.
STELZER
SLS Life Science Agitator
The Stelzer SLS life science agitator is a compact low-height unit designed for the needs of the pharmaceutical industry, the biotechnological sector and the food industry. Stelzer SLS life science agitator satisfies all relevant standards such as GMP and FDA requirements. A hygienic-design double-acting mechanical seal warrants effective product containment. Stelzer SLS life science agitator fits even on a very small vessel due to the unique integration of the mechanical seal in a stainless steel body.
STELZER
SKR Coaxial Agitators
The SKR coaxial agitator is a high-performance unit equipped with two impeller systems each with an independent drive and control system. SKR coaxial agitator integrates several processes in one unit. The client benefits from shorter batch processing times, increased plant throughput and reduced vessel, pump and heat exchanger costs.
The SKR coaxial agitator are fit for operation in explosive atmospheres
STELZER
CFD-Simulation
CFD simulations are used at STELZER Rührtechnik for conceptual studies of new designs, product developments and verification of agitator engineering design and supplementation of tests under realistic conditions in the laboratory. They can be used to simulate tests that are not possible with real media for safety reasons. This may be due to toxic, explosive or carcinogen effects of the product.
We use CFD simulations to assess the flow conditions in the vessels and determine whether a given agitator will perform as required. It is a further advantage that the model is running using the actual dimensions and not the model dimensions. The combination of the CFD investigations with conventional agitator software ensures maximum safety regarding the process engineering design for the agitator. In brief: Belt and braces.
STELZER
Technology laboratory
A laboratory with modern equipment is available for our tests. Suitable testing areas, already equipped with glass and stainless steel vessels in different sizes, are available for all test arrangements. The vessels can be optionally heated or cooled. Our standard agitators of various kinds include axial, radial, tangential and countercurrent flow impellers. They cover a viscosity range up to 1 million mPas.
A testing area with a coaxial agitator system is available as well. It provides optimal test conditions for tests with two agitator systems running in the same or in opposite directions. The measuring data of the practical tests are continuously registered to provide a basis for later scaling-up to original size.
