Underground Shotcrete Sprayer

Saner SRHTP25-10-45S/A6 is a compact, piston-powered underground shotcrete sprayer engineered for concrete wet-spraying and high-pressure grouting in confined headings.

The open dual-pump system delivers a constant 10Mpa pressure for stable, long-distance aggregate pumping.

The standard dual-jet nozzle configuration achieves a 25m³/h output to optimize underground lining efficiency.

The ultra-low chassis at 1.9m in height allows fluent positioning inside low-ceiling mines and utility tunnels.

The high-wear S-pipe valve paired with long-stroke cylinders eliminates slurry leakage to smoothly process large aggregates.

CE Directive 2006/42/EC Certified: Complies with EU machinery safety standards for legal global site access.

Underground Explosion-Proof Certified: Electrical components conform to underground hazard codes for certified site entry.

IP65 Ingress Protection Certified: Enclosures pass mandatory waterproofing audits to withstand high-humidity environments.

Kawasaki Hydraulics Certified: Core pump source passes factory quality audits for verified volumetric efficiency under heavy loads.

Tailored Modification

Custom engineering of electrical configurations and chassis dimensions prior to shipment to match your local voltage variances and hazardous ratings.

Remote Calibration

Technical experts deliver 1-on-1 multilingual video guidance for initial line piping, chemical ratio calibration, and shotcrete tuning.

Rapid Spares

Overseas hubs maintain constant stocks of genuine wear nozzles, wear plates, and high-pressure concrete lines, shipping within 48 hours of order.

Q1: Will the remote control suffer from signal dropouts or lag inside deep, confined underground headings?

A: No. The remote integrates an enhanced mining-grade anti-interference transceiver, securing stable signal penetration with a response time ≤100ms.

Q2: The 45KW electric motor operates under unstable voltage conditions underground; is it prone to burnout?

A: No. The power circuit is fitted with a heavy-duty wide-voltage breaker and thermal overload relays to automatically trip and shield the motor from voltage spikes.

Q3: Can this unit switch between shotcrete spraying and high-pressure grouting without swapping internal lines or valves?

A: Yes. The operator can toggle functions via the main hydraulic control valve; the standardized internal flow channel requires no mechanical teardown.

Q4: With a Ф160mm cylinder bore, will oversized aggregates cause frequent blockages or mechanical jams inside the valve?

A: The hopper features a rigid 16mm steel screen to block oversized rock. Combined with the 10Mpa high-pressure thrust, the system forces through minor aggregate packing effortlessly.
