Putzmeister Industrial Pumps

As an exclusive representative, we offer technology for transporting materials that are unpumpable for conventional pumps. We focus on hermetically sealed conveying without odors and leaks. The Putzmeister component system is modular and always tailor-made to specific requirements.

Industries and Industrial Applications

• Waste Management and WWTP: Safe and closed transport of dewatered sewage sludge, biowaste, and hazardous waste, preventing odors and leaks.
• Power Generation and Heating: Incineration of dewatered or pre-dried sewage sludge in existing power plants, heating plants, and incinerators. Efficient and reliable transport of abrasive fly ash and biomass.
• Cement Plants: Transport of waste and alternative fuels for direct co-incineration in cement plant kilns.
• Chemical Industry: Pumping of highly viscous and challenging materials while ensuring perfect hermetic sealing of the entire process.
• Steelworks: Pumping of coal tar, blast furnace sludges, and descaling sludge.

High-Density Solids Pumps Portfolio

KOS – Piston Pumps with S-Transfer Tube

For high-density sludges (such as dewatered sewage sludge) containing solid particles. The valveless design with a large free passage ensures reliable operation even for materials containing foreign bodies. Capacity 10–400 m³/h, pressure up to 150 bar.

HSP – Piston Pumps with Seat Valves

For fine-grained pastes and high pressures. Precise sealing enables pumping at high pressures, with the option for pulsation-free operation. Capacity 10–400 m³/h, pressure up to 150 bar.

KOV – Piston Pumps with Ball Valves

Designed for liquid to paste-like mixtures without solid particles. A compact and economical solution for clean mixtures. Capacity 0–70 m³/h, pressure up to 80 bar.

EKO – Single-Cylinder Piston Pumps

For large-volume and stiff materials. They utilize a forced-feed system where the piston actively pushes the material into the delivery system. Ideal for extremely dewatered paper sludges, crushed steel barrels with hazardous waste, WWTP screenings, food including packaging, and biomass. Capacity up to 14 m³/h, pressure up to 100 bar.

Other System Components

• Silos and Bunkers: Silos and receiving bunkers from 10 to 1000 m³ equipped with hydraulic sliding frames, ensuring highly efficient material extraction from circular and rectangular silos, and augers for continuous dosing.
• Feeding Equipment: Twin-shaft auger feeders (THS) for homogeneous filling of the pump cylinders and creating pre-pressure in the hopper.
• Foreign Body Separator: Equipment installed in the pipeline downstream of the pump, designed to retain undesirable foreign bodies.
• BLI Station (Boundary Layer Injection): A high-pressure unit designed to inject lubricant into the boundary layer of the pipeline. This injection significantly reduces passive resistance and friction of pumped sludges in the pipeline (reducing energy consumption by up to 80%), thereby increasing the overall efficiency of long-distance material transport.
• Pulsation Dampers: Equipment for eliminating pressure surges in pipelines, ensuring a smooth flow of material (preventing water hammer effects in sludges with a low dry solids content).
• Drives and Control: Industrial hydraulic power packs (HA) and combined control cabinets with PLC controls.
