Close-Coupled Vacuum Pump 4.0kW 5.5HP

The Close-Coupled Vacuum Pump 4.0kW 5.5HP is a water pump (water pump motor) product and a gas pump operating in a vacuum environment. The pump features an optimized design, efficient operation, smooth operational design, and performs well in the industrial sector.

General design of the Close-Coupled Vacuum Pump 4.0kW 5.5HP

The vacuum pump belongs to the 3-phase water pump series, designed with an eye-catching dark blue appearance. The pump casing is made of cast iron or stainless steel. The motor is designed with the pump head and electric motor, specifically a 3-phase electric motor integrated into a single block, making it very compact and suitable for space-limited areas.

Structure of the Close-Coupled Vacuum Pump 4.0kW 5.5HP

The Close-Coupled Vacuum Pump 4.0kW 5.5HP has a compact coaxial design, consisting of two main parts: the electric motor and the vacuum pump head. Detailed structure includes:

• Electric motor: Uses a 4.0kW (5.5Hp) motor typically using 3-phase voltage (380V), with a cast iron or cast aluminum outer casing for good heat dissipation, pure copper wire winding, and an integrated rear cooling fan.
• Vacuum pump head: Consists of a pump chamber containing an impeller system (or piston/oil ring depending on the type) made of high wear-resistant alloy. This part is responsible for suctioning air or gas to create a negative pressure environment.
• Pump shaft and mechanical seal: The stainless steel shaft transmits power directly from the motor to the impeller, combined with a high-temperature and high-pressure resistant mechanical seal to prevent air from entering the pump chamber.
• Coupling and base: Details connecting the motor and pump head on a sturdy base frame, helping to reduce vibration during operation.

Operating instructions for the Close-Coupled Vacuum Pump 4.0kW 5.5HP

System installation

• Machine placement: Place in a dry, cool place, on a flat and securely fixed surface.
• Electrical connection: Install an electrical panel with magnetic contactor and thermal overload relay for overload protection.
• Rotation test: Flick the switch on and off to check the motor rotation direction according to the arrow on the machine body.
• Pipeline connection: The suction pipe must be absolutely tight; it is recommended to install a check valve and dust filter.

Start-up and operation process

• Step 1: Open all valves on the suction and discharge pipes.
• Step 2: Supply cooling water (for water ring pumps) or check oil circulation (for oil ring pumps).
• Step 3: Press the Start button on the control panel.
• Step 4: Listen to the operating sound; the machine must run smoothly without abnormal noise.
• Step 5: Monitor the pressure gauge to check if the required vacuum level is achieved.

Shut-down process

• Step 1: Close the shut-off valve on the suction pipe to prevent oil or water from being sucked back into the system.
• Step 2: Press the Stop button on the control panel.
• Step 3: Close the cooling water supply (for water ring pumps).
• Step 4: Drain all liquid in the pump chamber if the machine is stopped for a long time during winter.

The Close-Coupled Vacuum Pump 4.0kW 5.5HP is suitable for many production systems requiring stable vacuum generation, continuous operation, and high durability.
