Klein GmbH / KLEIN Pumpentechnologie Concrete Pumps

Engineering and supply of Klein GmbH / KLEIN Pumpentechnologie twin-piston concrete pumps, shotcrete spraying units and industrial slurry pump components.

Stationary concrete pumps KTP Klein GmbH / KLEIN Pumpentechnologie

Twin-piston stationary concrete pumps of KTP 150, KTP 180 and KTP 220 series are engineered for continuous placement of heavy concrete mixes at high elevations and long distances in civil engineering. The rigid frame dampens cyclical pulsation during pumping strokes.

  • Concrete placement with aggregate sizing reaching up to sixty-three millimeters
  • Hydraulic operating pressure up to one hundred thirty bar for high-rise pumping
  • Smooth hydraulic control preventing shock pulses during stroke reversing cycles
  • Rapid access to delivery cylinders and flushing chamber for routine maintenance

Shotcrete spraying pumps Klein GmbH / KLEIN Pumpentechnologie

Specialized Spritzbetonpumpen concrete spraying pumps and mobile manipulators are developed for tunnel driving, mine gallery reinforcement and underground construction. Compact envelope dimensions ensure superior agility within constrained subterranean headings.

  • Precise setting accelerator dosing synchronized with concrete delivery output
  • Uniform pulse-free flow providing optimal compaction of sprayed concrete layers
  • Seamless integration with telescopic spraying booms and robotic manipulators
  • Drive configurations with protected diesel or flameproof electric power units

Industrial solids pumps Dickstoffpumpen Klein GmbH / KLEIN Pumpentechnologie

Twin-piston industrial Dickstoffpumpen solids pumps are designed for pumping paste-like, slurry and high-density sludge in mining, metallurgy and wastewater treatment facilities. The pumps reliably convey viscous media containing extremely high dry solids content.

  • Transfer of thickened mine tailings, abrasive paste and dense drilling slurries
  • Working chamber geometry preventing sludge stratification and residue buildup
  • Special wear-resistant chromium alloys for pumping barrels and sealing packings
  • Direct intake coupling with storage feeding hoppers and screw delivery augers

Trailer and crawler pumps Klein GmbH / KLEIN Pumpentechnologie

Mobile concrete pumps mounted on road trailers and tracked undercarriages deliver autonomous performance at remote construction sites lacking paved surfaces. The crawler chassis enables navigation across soft soil and steep slopes during bridge and dam projects.

  • Reinforced road trailer chassis with air braking and compliant road lighting
  • Heavy crawler undercarriages with independent hydrostatic planetary track drive
  • Hydraulic outrigger stabilizers ensuring firm leveling during maximum pumping
  • Integrated pressurized water tanks and air cleaning ports for pipe washdown

Hydraulic power packs Klein GmbH / KLEIN Pumpentechnologie

Hydraulic power packs manufactured by Klein GmbH feature variable displacement axial piston pumps, control manifold blocks and fluid coolers. The hydraulic units drive main concrete pumping cylinders, switching valve linkages and auxiliary equipment.

  • Energy-efficient main pumps featuring load-sensing pressure-flow regulation
  • Hydraulic fluid filtration down to ten microns with clogging alarm indicators
  • Independent air and water heat exchangers for continuous heavy-duty shifts
  • Proportional directional control valves enabling smooth reversing actuation

Valves, pistons and seal kits Klein GmbH / KLEIN Pumpentechnologie

To preserve output capacity of pumping systems, Klein supplies wear components: poppet seat valves (Sitzventil), S-tubes, polyurethane concrete pumping pistons and seal rings. Parts are engineered for extreme friction against abrasive crushed rock and quartz sand.

  • Seat poppet valves fitted with hard metal seats ensuring tight sealing shutoff
  • Concrete delivery pistons molded from high-tensile reinforced polyurethane
  • Cylinder packing rings and wash box seals with heat-resistant elastomeric lip
  • Tungsten carbide hardfaced wear rings and spectacle plates for extended life

Design engineering of twin-piston concrete pumps Klein GmbH / KLEIN Pumpentechnologie

Twin-piston stationary and trailer-mounted concrete pumps manufactured by Klein GmbH / KLEIN Pumpentechnologie in Jettingen-Scheppach are engineered for heavy-duty placement of dense concrete mixes under elevated pressure levels.

The mechanical reliability is grounded in a symmetrical hydraulic drive layout synchronizing delivery cylinders with the oscillating distributor tube. Smooth piston movement eliminates pressure spikes inside delivery piping while reducing structural vibrations across placing booms.

The inner surface of concrete conveying cylinders is precision hard-chromed to withstand severe friction caused by quartz sand and crushed rock.

An automated centralized grease lubrication pump injects lubricant into bearing bushings and sealing assemblies, preventing cement slurry ingress into the hydraulic loop and extending maintenance intervals during continuous operational shifts.

Shotcrete spraying technology and Spritzbetonpumpen units for tunneling

For underground excavation and gallery wall stabilization, specialized Spritzbetonpumpen shotcrete pumps deliver continuous layers of sprayed concrete against rock formations propelled by compressed air.

The key performance benefit of Klein spraying machinery is an exceptionally uniform material flow devoid of pulsation, which achieves dense crack penetration and eliminates separation of freshly applied lining.

An integrated chemical dosing assembly meters liquid accelerators in strict synchronization with pump stroke velocity.

Whenever concrete output adjustments occur, additive injection rates adapt automatically, preserving target compressive strength parameters and minimizing rebound material loss in demanding mine headings and rail tunnel profiles.

Industrial slurry transfer and viscous sludge transport via Dickstoffpumpen

Twin-piston Dickstoffpumpen industrial pumps are tailored to convey high-density slurries, dewatered municipal sludge and abrasive tailings across metallurgical and processing plants.

Featuring enlarged suction manifold diameters and conical receiving hoppers, these pumping assemblies reliably intake thixotropic media characterized by high dry solids content without risk of cavitation.

The hydraulic power circuit with electronic position feedback maintains constant thrust throughout the delivery stroke.

When required, pump skids are coupled with receiving hoppers fitted with twin forced-feed augers, preventing bridge formation of viscous paste above the suction chamber and optimizing continuous intake volume into downstream discharge piping.

Poppet seat valve systems and wear-resistant distribution components

Klein pumping machines utilize heavy-duty seat valves (Sitzventil) and robust S-tube swinging linkages to govern material flow switching.

Seat valve assemblies prevent mechanical jamming when handling coarse aggregate concrete, as valve discs close with high sealing thrust, cleanly shearing aggregate fragments while maintaining positive pressure retention inside delivery cylinders.

High-friction friction surfaces including sealing wear rings, spectacle plates and valve seats are hardfaced with tungsten carbide layers.

Timely replacement of guide rings and high-tensile polyurethane delivery pistons prevents fine slurry leakage into the water wash box, thereby shielding expensive chromium-plated cylinder barrels from premature score marks.

Hydraulic drive architecture, oil conditioning and proportional control

The hydraulic powertrain of Klein machinery is built around variable displacement axial piston pumps operating in closed or semi-closed circulating loops.

Electronically controlled proportional directional valves decelerate piston travel gently before end stroke limits, dampening frame vibrations and avoiding hydraulic shock loads throughout high-pressure piping circuits.

Multi-stage oil filtration featuring electronic differential pressure sensors paired with high-capacity heat exchangers ensures hydraulic fluid operating temperatures remain stable during round-the-clock concrete placement in hot summer climates.

Fast-acting relief valves shield drive motors and hydraulic manifolds from surge pressures if delivery line blockages emerge.
