1. Structural features
The robust construction of the grouting pump encompasses an array of components including a three-phase asynchronous motor, coupling, plunger pump, oil tank, overflow valve, electromagnetic directional valve, oil cylinder, grouting cylinder, valve chamber, and a mechanical directional mechanism. It is equipped with a high-pressure rubber hose, return oil pipe, water cooler, suction pipe, suction nozzle, discharge pipe, and mixer, ensuring optimal performance and durability.
2. Working principle
Harnessing the power of a sophisticated electric motor, the grouting pump drives the plunger pump via a coupling, drawing hydraulic oil from the reservoir into the pump. The expelled high-pressure oil is channeled through an overflow valve, directional valve, and high-pressure piping to the oil cylinder, propelling the piston in a synchronized back-and-forth motion. This cyclical process incorporates cooling via a water cooler and culminates in the precise injection of slurry through meticulously designed pipelines and valve chambers.
3. Main structural features
(1) Designed for operational ease, the pistons, piston rings, piston rods, and sealing rings within the oil and slurry cylinders are crafted individually for effortless cleaning and replacement.
(2) Featuring a metal proximity sensing mechanism, this pump activates the electromagnetic directional valve by detecting the piston's motion, ensuring precise directional control.
With hallmark characteristics of agility, speed, precision, and dependable switching, this mechanism defines operational excellence.

1. Hexagonal screw for card block
2. M27 fastening screw
3. Strong throat clamp

Safety Warning:
1. Ensure all rubber hoses strictly adhere to the MT98 standard for optimal safety.
2. Prior to pump activation, rotate the relief valve pressure handle counterclockwise to its limit for a safe, zero-pressure start. A limit pin must remain on the pressure handle; any unauthorized removal is strictly forbidden. Overpressure operation is averted by maintaining overflow valve settings at or below the pump's nominal pressure. During rated conditions, the pump should exhibit no leakage, with noise and vibration levels within normal ranges. Halt operations immediately if anomalies arise for prompt troubleshooting.
3. Refrain from unauthorized replacement of control components to ensure safe and efficient operations.
4. Both hydraulic and slurry systems generate high pressures. To avert accidents, conduct any disassembly or assembly of components only after pump shutdown and depressurization. Equipment repair or maintenance under load is strictly prohibited.
5. Powered by hydraulic pressure, the grouting pump's working pressure must remain within the set limits during operation to ensure safety and longevity.
6. To ensure seamless operation and safety, never initiate the system under load or pressure conditions. Always make sure the system is in an unloaded state before engaging.
7. Confirm the motor's direction is correct before proceeding, as this is critical for officially starting and operating smoothly in a normal production environment.
8. It's essential to have personnel present to oversee the operation of the grouting pump, ensuring safety and efficiency during its usage.
9. Upon completing the grouting process, promptly clean the grouting pump and thoroughly drain any residual liquid. This step is vital to prevent any blockage in the pipeline and maintain peak performance.
