EISELE – pump and machinery production based on experience and tradition
Hailing from the Swabian town of Sigmaringen, family company Franz EISELE & Söhne GmbH u. Co. KG offers a diverse range of products for energy-producing farmers, and specialises in the storage, conveyance, homogenisation, spreading and transportation of liquid manure. Biogas plant components complete the product range, and have been built by EISELE for over 25 years. These include submersible motor-driven agitators with gas-tight operation in various models:
- for concrete floor digesters which either have a drive-over ramp or a quick access cover with a lifting device
- for containers with membrane gas holders, the range includes a lateral access model which offers the possibility of automatic extension and retraction of the agitator. Thanks to a service shaft with an upward-opening cover, the agitator can be removed from the digester for servicing without it becoming necessary to uncover the gas holder.
EISELE submersible agitators are available with output ratings of between 2.2 and 15 kilowatts. Only devices with power outputs of 7.5, 11 or 15 kilowatts, however, are used in biogas plants, whereby 11 and 15 kilowatt agitator models are also available with ATEX certification for explosive atmospheres. All fittings are manufactured from stainless steel and the motors are constructed by EISELE.
Thanks to their versatile application potential, vertical, submersible motor and rotary pumps ensure the flawless mixing and pumping of liquid manure or fermentation substrate and are supplied with power outputs ranging from 7.5 to 22 kilowatts (bespoke models on request). Its extensive range of pumps therefore allows EISELE to satisfy all the requirements of agricultural operation.
A combined overpressure/underpressure safety device made from stainless steel guarantees safe pressure within the fermenter and thus gives it protection.
