2. Sequence 750 Series - 4200gph (Water Pump)

Sequence centrifugal pumps are the most energy efficient water pumps available. The amount of water volume moved (gph) versus the amount of electrity they use is incredible. Sequence centrifugal pumps are designed and built to meet the special needs of ponds, waterscapes, aquaculture and large hydroponic systems. Buying "quality" really pays. Not only do you get years of dependable service, but you enjoy tremendous savings on your electric bill, every month. These are the work horses of the industry. They provide tremendous flow rates, with enough pressure (head) to handle the requirements of most systems with biological filters and moderate height waterfalls. They are also used extensively for the transfer and re-circulation requirements of filtration systems, water features, streams, fountains, hydroponic systems and aquaculture. Out-of-pond construction - NOT Submersible! Less than half the watt draw of comparable submersible pumps Ports are 2" FNPT suction and 1.5" FNPT discharge. Units are pre-wired with an 8' cord and molded 115V plug. Units can now be wired for 230V.Housing is molded of high strength, glass filled polypropylene. Quiet operation Dry run resistant mechanical seals. Stainless steel hardware is standard. The motors are TEFC, for excellent protection. Motors are aluminum for added weather resistance.
