Air Pump

Quality Korean Hook & Claw vacuum pumps for the Dairy Farm industry in New Zealand Korean manufactured Wonchang pumps are dry running (use no oil or water), compact and direct driven by high efficiency electric motors. The air suction volume is controlled via a variable speed driven motor which determines the volumetric flow delivered to the milking machine. All vacuum pumps in this industry are rated in free air at -50kPa vacuum level. Working vacuum levels are typically between -44 kPa through to -50kPa. Claw pumps are energy efficient and in conjunction with the variable speed drives significant cost savings can be made. As an example, a Liquid ring vacuum pump installed with no variable speed drive has an adsorbed motor power of 15kW and a delivered flow rate of around 4000 l/min. A system with 4000 l/min flow requirement has a built in reserve capacity and is regulated by an adjustable vacuum regulation valve (bleeds in air from atmosphere) to maintain a constant vacuum level. If you replaced the above pump with a dry running VCX 500 Hook & Claw vacuum pump without a variable speed drive, it would require 11kW motor power and deliver a flow rate of 4300 l/min. When you add the variable speed drive, you will achieve further motor power saving with the average adsorbed power diving as low as 9kW. Thats a huge saving of 6kWs per hour multiplied by your kWh unit price for every operational hour of your plant! As an illustration, with a 6kW motor power saving and a unit …
