The vacuum system consists of vacuum pumps, pressure stabilization tanks, gas–liquid separators, and connecting pipelines. The vacuum pump generates a vacuum, which is then distributed to each sand box via a vacuum distributor, providing sufficient suction to prevent the mold sand from collapsing during pouring.
I. System Components and Functions
1. Vacuum Pump
The 2BE series water-ring vacuum pumps are high-efficiency, energy-saving products developed by our company based on years of research, production experience, and advanced imported technologies.
Function: Used to extract air or other non-corrosive, water-insoluble gases to create a vacuum or maintain process-required pressure in a sealed container.
Purpose in Casting: Provides the vacuum needed during pouring, ensuring a stable vacuum field in the sand boxes.
2. Pressure Stabilization Tank & Gas–Liquid Separator
Function: Filters solid particles from the extracted gas using water, stabilizes vacuum pressure, separates gas and water, and further removes solids from the air before discharge to prevent air pollution.
Benefits: Maintains a stable and reliable vacuum; the vacuum pump operates efficiently with low wear, high durability, and easy maintenance.
3. Application in Sand Boxes
Vacuum extraction removes air between sand grains, compacting the sand and forming a stable mold inside the sealed sand box.
During casting:
Accelerates gas evacuation and reduces total gas volume.
Lowers gas pressure at the metal–mold interface.
Speeds up the advancing metal flow front, improving mold filling.
Reduces surface carbon defects.
Suppresses combustion of foam pattern materials, promoting gasification.
Improves the environment, increases metal fluidity, moldability, and clarity of casting contours.
Higher vacuum levels further suppress foam pattern combustion, accelerate pyrolysis and decomposition, shorten residence time of pyrolysis products in high-temperature zones, and reduce the likelihood of deep pyrolysis.

Note: Pumping capacity, speed, and power are ranges. The performance of a single water-ring vacuum pump varies with its rotational speed. Example: Model 2BE1-253-820 (speed) – 75 kW has a maximum pumping capacity of 42.7 m³/min.
This system ensures stable vacuum creation, optimal sand compaction, improved casting quality, and environmental safety in lost foam and precision casting processes.
