110V 7CFM Dual-Stage Rotary Vane Vacuum Pump 3/4HP 1720r/min 370ml Oil Capacity

  
110V 7CFM Dual-Stage Rotary Vane Vacuum Pump 3/4HP 1720r/min 370ml Oil Capacity. The rotary vane vacuum pump is essential equipment used to extract gas from airtight containers.

It can operate independently or as a pre-pumping pump for booster pumps, diffusion pumps, molecular pumps, maintenance pumps, and titanium pumps. Applications include manufacturing electric vacuum devices, vacuum welding, printing, plastic absorption, refrigeration equipment repair, and instrument matching. The dual-stage vacuum pump is compact, lightweight, and features a large oil window for easy oil volume monitoring during refills. The oil mist catcher has a five-layer filtration system that effectively prevents oil splashing and reduces noise.

Ensure the oil level is within the center of the oil pointer when the pump is stationary. Low oil levels can impact the vacuum degree by not sealing the exhaust valve, while high levels may cause fuel injection during atmospheric starting. Addition of oil should be filtered to prevent debris from entering. The pump can be started in either atmospheric or any vacuum condition.

If a solenoid valve is present at the pump port, it should operate simultaneously with the pump. High ambient temperatures lower the oil viscosity leading to decreased limit vacuum. Proper ventilation, heat dissipation, or improved pump oil performance can mitigate this effect. Verify pump's limit vacuum using a compressed mercury vacuum gauge after a stable pump temperature is reached. Gauge readings may vary due to pump oil, gauge error, and should be utilized as a reference point. Open the gas ballast valve if the environment is warm or extracted gas contains condensable steam. After 20-40 minutes, close the valve and before shutdown, run the pump without load for 30 minutes to prolong pump oil lifespan. Oil selection plays a crucial role in starting power and vacuum limit. Different oil viscosities affect pump performance differently.

Select oil as per specific requirements, considering factors like viscosity and saturated vapor pressure. 110V 7CFM Vacuum Pump 1. Orders are processed from Monday-Friday; Not on the weekends & public holidays.
