One of the favorites is the Sequence 1000 Pump series that can push water up to 6100 US GPH and pressures up to 23 feet maximum depending on which 1000 series you choose.
Out-of-pond construction - Sequence Pumps are NOT Submersible! Less than half the watt draw of comparable submersible pumps. 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. Rebuildable, industrial grade motors.
