Putzmeister SP 11 LMR worm pump (Stage V) at bauma 2025 in Munich

The SP 11 LMR is specially designed to meet high requirements for ease of operation and delivery rate. It is therefore ideal for plasterers and stucco plasterers, who value efficient and continuous processing of premixed dry mortar and site mixes. From Monday 7th April to Sunday 13th April, visitors will be able to see these powerful machines in the flesh in Hall B6 of bauma in Munich.

Efficiency and output are paramount for these worm pumps. It starts with the convenience of filling the lifting mixer. The large hopper and low filling height enable the material to be continually mixed. The enormous capacity therefore offers a significant reserve even for tasks with a large scope. Depending on the required delivery rate and properties, the SP 11 LMR processes a wide variety of materials with a particle distribution of up to 6 mm – whether as a site mix or as a bagged internal or external plaster. It can work with fine plaster, lime cement plaster, base or decorative plaster, light masonry mortar, fire-resistant mortar and mortar for filling and injection tasks.

Not reliant on power sources
The three-cylinder Stage V motor meets current exhaust regulations and delivers a full 16.3 kW. With a lower speed of rotation and the double-shell hood for optimum sound insulation, it is particularly quiet during operation – and as it does not require a power connection it can be set up flexibly on any construction site. In conjunction with the powerful 2L6 worm pump with pressure connections for hose connections, it allows for delivery distances up to 60 m and delivery heights up to 40 m. 

Clear and uncomplicated
The clearly laid out operating panel enables users to control the machine easily and safely in accordance with CE standards. The output and water metering are infinitely variable. The pumping and mixing drives are fully hydraulic, allowing for infinite selection of pumping outputs up to 60 l/min. Additionally, the water metering pipe in the mixer cover prevents blockages and compactions in the machine. Optional dust extraction is a clever solution: The extracted dust is blown out through the exhaust system. 

Fully equipped
The powerful 2L6 worm pump with M 50 pressure connections is included as part of the standard equipment. The high-pressure cleaner and cleaning accessories, lever press with hose, a car coupling and a car cable adaptor are also factory standard, among others. There are also optional additional features: For example, the working light, radio remote control, truck coupling and screen grille.
