The 301 pressure pump is  based on the legendary Rena 301 pressure pump. This is a great pump for industrial applications. The new deluxe version is now made in the USA and  has a convenient on/off switch mounted in the case and the flow level is now controlled by the same dial as the vacuum (BE3011) version. The BE301 is also UL approved (medical device). Known for its power and reliability this pump has replaced pumps costing twice as much in many commercial applications. It's simple design, easy maintenance, rugged construction and economical price makes this a great choice for a variety of applications.
Uses: aquariums, ponds, bubble walls and bubble sculptures, laboratory equipment, water purification, aeration, liquid agitation, air sampling and other uses where a steady flow at lower volumes and pressure are needed.
