- 4 kW
- Conveying hose ID
- 38 / 32 mm
How it works & where it is used
The GZ-3ER/S combines an electric rotor gunning machine with a water pump and automatic lubrication equipment. The published configuration has a 6.3 L rotor and a 1.5–3 m³/h output range. PLC control, a variable-frequency drive and an air-pressure sensor are described for delivery-line blockage management. Sector-shaped rotor openings distinguish this version from the standard GZ-3ER.
Kiln, boiler and furnace lining projects; steel, cement and petroleum plant maintenance.
Designed around the material flow
- PLC and variable-frequency machine control.
- Sector-shaped rotor body and rigid liner.
- Integrated water pump rated at 26 L/min with 70 m head.
- Automatic lubrication unit with a 2 L reservoir.
- High hopper, bag cutter, vibrator and dust collection bag.
- Pre-dampening nozzle, solid wheels and protected control cabinet.
Combining water supply and gunning equipment on one machine can simplify site positioning. Automated lubrication supports routine seal maintenance. Pressure-sensor control is a blockage-management feature; it does not establish blockage-free operation or replace the operating procedure.
Structure & installation
Installation planning: Confirm compressor delivery, hose routing, nozzle water supply and drive requirements. Conveying distances depend on the actual installation.
Pending confirmation. A model-specific installation drawing, interface dimensions and electrical diagram have not been supplied. Request these for the offered configuration. Product photographs do not replace installation drawings.

Air, power & conveying boundaries
Air-pressure values describe the pneumatic system, not the pressure of a hydraulic pump. Do not assume maximum output and maximum conveying distance can be achieved simultaneously.
Information needed for selection Request the electrical load schedule, water supply requirements and blockage-management instructions. Confirm the maintenance procedure and lubricant specification for the seal lubrication system.
Pending confirmation. A verified performance curve or material trial record is not available. Maximum values must not be assumed to occur simultaneously.
Configuration & maintenance
Items requiring confirmation The source labels 1.5–3 m³/h as maximum output. Confirm operating range, control sequence, PLC functions and the supplied hose size. Do not treat the 4 kW rotor motor as total installed electrical power.
Pending confirmation. Confirm the standard accessory list, consumable parts and operating instructions for the exact build. Confirm the hose diameter, hose length, nozzle and whether a water pump is included.
Documentation & evidence
Pending confirmation. No model-specific independent test report or verified project case has been supplied for this representative page. Product certification applicability, document validity and public display permission remain to be checked. No certification or service-life guarantee is implied.
Quotation & support scope
Packaging, minimum order quantity and lead time: Not established in the cited technical data. Request the packing method, packed dimensions, gross weight, order quantity and delivery schedule in the quotation. Machine dimensions and weight are not shipping measurements.
Also confirm the standard accessory list, consumable parts, warranty, commissioning support, packing, MOQ and lead time. No certification, factory production capacity or quantified service-life claim is added without supporting records.
