Water Circulation Vacuum Pump This Circulation and Vacuum Pump combines the best of both worlds by using the circulating water to pull a vacuum which requires no oil at all and has very low maintenance requirements overall due to this unique process and design. Each vacuum port on the unit pulls vacuum separately from one another so the user can use it for different applications at the same time or combined to increase the vacuum. This pump will also circulate water through the backports as needed to cool and application and dissipate heat as needed. Specifications Vacuum Degree 0.0980Mpa (735 Torr) @ 25°C Single Tap Exhaustion 10L/min Voltage 110V / 50Hz USA Plug Noise <50DB     Specifications Number of Vacuum ports: 2qty (independent vacuum po Vacuum Port Size: 3/8" Vacuum Depth: 16 torr Number or Water Circulation inlet: 1qty Number or Water Circulation Outlet: 1qty Pumping Speed: 6.5 L/min Reservoir Capacity: 12L Overall Dimensions: 15.5" x 11.5" x 17" Decibel: 62 dB Weight (no water): 17lbs 10oz

NOTE: Models 40 GPH-160 GPH contain a steel shaft and are not suitable for saltwater applications. Larger pumps (250 GPH-1000 GPH) have a ceramic shaft, and these are suitable for saltwater operation.  Choose a pump that was built to go below the waterline! Active Aqua's entire collection of pumps complete any grow setup. You can't beat the submersible line, as it is built for hydroponic systems. All of Active Aqua's submersible pumps include multiple hose fittings so you get an exact fit every time. Each pump's powerful mag drive construction includes removable foam filters, impellers, rubber mounting feet to reduce vibration, and a 6-foot heavy duty power cord. Adjust the pump's flow to get things moving at your preferred rate. Specifications 250 gallons per hour, recommended for 25 gallon reservoirs, 16 Watts/120 VAC 400 gallons per hour, recommended for 40 gallon reservoirs, 24 Watts/120 VAC 550 gallons per hour, recommended for 55 gallon reservoirs, 33 Watts/120 VAC 800 gallons per hour, recommended for 80 gallon reservoirs, 58 Watts/120 VAC 1,100 gallons per hour, recommended for 100+ gallon reservoirs, 92 Watts/120 VAC Features Oil free and environmentally safe BPA free—safe for aquaponic use One year warranty 6' power cord UL-listed   NOTE: Models 40 GPH-160 GPH contain a steel shaft and are not suitable for saltwater applications.
