What STS Scheltzke does

STS Scheltzke GmbH & Co. KG is a German family-owned manufacturer specializing in high-tech mixing systems and feed pumps for injection, anchoring, and drilling technology in demanding specialized foundation engineering (Spezialtiefbau). The company operates from a modern manufacturing facility in Trebur, Germany, and is co-led by managing directors Hans-Georg Scheltzke and Sven Scheltzke. Its product portfolio is organized as a modular system: injection pumps (IP) and high-pressure pump stations (HPS) form the core pumping components, complemented by mixing stations (MS, MRS), mixing pump stations (MPS), container-based mobile units (IPC, MPC), conveyor screws (FS), stirring stations (RS), and digital monitoring accessories (RMS data recorders, DMM flow meters, wireless remote controls up to 3000m range). Technical specifications include injection pressures up to 100 bar and flow ranges from 0.5-3000 l/min depending on configuration. Notable technology includes electro-hydraulic drive, hydraulic-controlled valves, inductive measurement technology, and multi-language touchscreen recording devices.

The company generates revenue through three streams: direct hardware sales of both standard series products and customer-specific custom solutions (Sonderlösungen), equipment rental for temporary project needs, and system components/accessories. Both purchase and rental go-to-market models are supported, with distribution handled through direct B2B sales worldwide. The customer base consists of specialized foundation engineering contractors and construction companies requiring robust machinery for geotechnical applications. The company claims worldwide deployment of its equipment and maintains a bilingual (German/English) website as its primary marketing channel. A documented custom development partnership with Marti Geotechnik GmbH demonstrates engagement in client-specific engineering projects.

Core offering

STS Scheltzke designs, develops, and serially manufactures high-tech mixing systems and feed pumps used in injection, anchoring, and drilling technology for demanding special foundation engineering (Spezialtiefbau). The portfolio spans injection pumps, high-pressure pump stations, mixing stations and containers, stirring stations, conveyor screws, and supporting instrumentation such as data recording and flow measurement devices. Both standard series products and customer-specific special solutions are offered, and equipment is also available for rental on a global basis.

Product overview

STS Scheltzke specializes in high-tech mixing systems and transport pumps for specialized foundation engineering in injection, anchoring, and drilling technology. The product portfolio is organized as a modular system where injection pumps (IP) and high-pressure pump stations (HPS) serve as core pumping components, complemented by various mixing stations (MS, MRS, MPS) and mixing pump containers (MPC) for material preparation. Container solutions (IPC, MPC) provide mobile configurations for on-site deployment. Supporting accessories include data recording devices (RMS) for pressure and volume monitoring, flow measurement devices (DMM) for process control, conveyor screws (FS) for material transport, and various accessories like wireless remote controls and pressure sensors. Custom solutions and special constructions are also offered alongside the standard serial product lines. Products are available for purchase or rental.
