Pump rental for maintenance shutdowns: key sectors and temporary solutions
Pump rental is a temporary solution designed to maintain operational continuity when an industrial facility undergoes a planned maintenance shutdown, experiences a breakdown or requires a bypass during maintenance work. In practice, it provides a temporary replacement for a main pump, supports a critical transfer operation or manages dewatering without interrupting the process.

How to size a stirrer for a biogas digester based on diameter, height and substrate type
Sizing a stirrer for a biogas digester involves more than considering volume alone. Diameter determines horizontal coverage, height defines vertical reach, and substrate type determines the risk of sedimentation, crust formation or loss of homogeneity. The practical consequence is clear: poor agitation can compromise process stability, increase stirrer energy consumption and raise total operating costs.

Guide to pumps for a biogas plant: types and applications in anaerobic digestion
In a biogas plant, choosing the right pumping technology is essential to maintain a continuous flow, prevent blockages and reduce costly downtime. Not all pumps handle sludge, silage, manure or solids-laden digestate in the same way, and this directly affects the reliability of the installation. The right pump does more than simply move the product: it protects the process, stabilises operation and helps the anaerobic digestion process perform as required.

Progressive cavity pump: operation, applications and selection guide
A progressive cavity pump is designed to handle fluids that are difficult to transfer using conventional pumping technologies, including sludge, highly viscous products, abrasive media and fluids containing solids.

Anaerobic digesters: design guide, tank types and industrial optimization
Anaerobic digesters have become a key solution for facilities where organic waste management, operational continuity and energy recovery go hand in hand.
