INDUSTRIAL VACUUM PUMPS
Rotary Screw Positive Displacement Vacuum Pump Technology
Positive displacement pumps create a vacuum by drawing the air or gas from a chamber through the intermeshing rotary screws and discharging back to the atmosphere. This continuous process flow moves gas at a constant speed, making it a stable and reliable choice for many industrial applications. Vacuum pumps are highly reliable and efficient, produce low noise, and some types can be used in harsh environments.

Vacuum pumps are highly reliable and efficient, produce low noise, and some types can be used in harsh environments.
One of the most reliable types of positive displacement pumps is the rotary screw vacuum pump. Similar to rotary screw compressors, vacuum pumps typically feature a pair of screws that rotate continuously and force gas into a chamber to increase its pressure. This technology provides stable, continuous operation to meet the needs of a range of commercial users. Controls are able to vary operating speeds to tailor production for their project or process requirements. This customization keeps energy use down, improving efficiency and saving you money.

Frequently Asked Questions
Rotary screw vacuum pumps use a pair of intermeshing screws that rotate continuously, drawing gas or air from the inlet chamber and discharging it back to atmosphere. This positive displacement process creates a consistent, stable vacuum by moving gas at a constant speed. The design delivers smooth, pulsation-free operation, making it a reliable choice for industrial applications that require steady process vacuum conditions and continuous, uninterrupted performance across extended operating periods.
Kaishan industrial vacuum pumps are used across a broad range of applications, including the manufacture of electronics and semiconductors, precision aviation instruments, and high-specification industrial equipment. Additional applications include metal processing, plastic injection molding, glass and stone cutting, printing, packaging, and bottling operations. Their combination of low noise output, stable vacuum levels, and reliable continuous performance makes them suitable for both process-critical and general-purpose industrial vacuum requirements.
A VSD adjusts motor speed in real time to match actual process demand, rather than running at a fixed speed regardless of load. Kaishan's VSD-equipped vacuum pumps use this capability to maximize energy efficiency across varying vacuum levels, consuming only the power required to maintain the target vacuum. This reduces electricity consumption significantly over time, lowering operating costs and improving the overall energy profile of the compressed air and vacuum system.
Kaishan industrial vacuum pumps include sophisticated microprocessor controls that continuously monitor operating performance. When performance falls below a specified threshold — such as a drop in vacuum level or a deviation from normal parameters — the control system automatically generates an alert for the operator. This early-warning capability helps maintenance teams respond before a situation escalates, reducing the risk of unplanned downtime and protecting connected industrial processes from costly interruption.
Yes. Low noise is a key design objective across Kaishan's vacuum pump range. Many models operate at noise levels low enough to hold a normal conversation nearby, making them well suited to environments where excessive noise disrupts operations or poses health and safety concerns. This is particularly relevant in electronics assembly facilities, laboratories, and food production environments where quiet, clean operation is a process requirement alongside reliable vacuum performance.
Kaishan vacuum pumps are engineered for low total cost of ownership through reduced maintenance requirements. Routine service typically covers lubrication checks, filter inspections, and periodic servicing of wear components at intervals tracked by the control system's built-in service time indicator. The microprocessor controls assist maintenance planning by monitoring operating hours and flagging scheduled service intervals, helping facilities shift from reactive to planned maintenance and extend the productive life of the equipment.
