Product Overview

Laboratory Circulating Water Vacuum Pump

A laboratory circulating water vacuum pump is a vacuum-generating device that uses circulating water as the working medium to create negative pressure. It is primarily used for laboratory operations such as vacuum distillation, vacuum filtration, vacuum drying, and vacuum concentration. It can replace traditional oil vacuum pumps, helping prevent oil contamination, and is a commonly used basic vacuum device in chemical and biological laboratories.

Working Principle

The pump uses an electric motor to drive an impeller, creating a high-speed water flow inside the tank and generating negative pressure. Air is drawn out of the connected system through the vacuum inlet and discharged through the water tank. The water can be reused in a continuous cycle, resulting in low operating noise and simple maintenance. This design makes the pump suitable for long periods of continuous operation.

Applications

Laboratory circulating water vacuum pumps are widely used in chemical synthesis, including vacuum distillation and solvent recovery; biopharmaceutical applications, such as vacuum filtration and as a backing pump for freeze-drying systems; environmental monitoring, including vacuum filtration of water samples; university teaching laboratories; and small-scale pilot plants. They are particularly suitable for routine laboratory applications that require a stable, clean vacuum source but do not need an extremely high vacuum level.

Circulating Water Vacuum Pump Selection Guide

When selecting a laboratory circulating water vacuum pump, several factors should be considered. A flow rate of 60–90 L/min affects air extraction speed, while a head of 8–12 m indicates the pump's water delivery capability. An ABS water tank with a capacity of 15–35 L can provide longer continuous operation when a larger tank is used. The number of vacuum inlets, typically 2–5, should match the number of devices that need to operate simultaneously. Power ratings of 180–370 W are available, with higher power generally providing greater pumping capacity. Other important features include a corrosion-resistant water tank, low-water protection, and noise control.

Customer Photos/ Customer Review

The circulating water vacuum pump operates smoothly, has sufficient negative pressure, fast filtration speed, corrosion-resistant material, long service life, and simple and convenient maintenance. The customer service communication is smooth, the logistics and delivery are fast, the transportation packaging is thick and bump-proof, the machine is delivered in good condition, and the overall reliability is good.

The vacuuming force is sufficient and the negative pressure is stable, which is sufficient for distillation and filtration. The circulating water design dissipates heat quickly and does not get hot during long-term operation. The dual-meter display has clear readings and is particularly simple to operate. The customer service is very patient and not perfunctory at all.

The operation is stable, the noise is low, and the air pumping speed is fast, fully meeting our experimental needs. The after-sales service is also in place. It will be better if we can produce larger ones in the future.
