Goulds 3700Standard Features for Optimum ReliabilityOptional 3700LF Design for Low-Flow Services Proven API 610 Nozzle-Load DesignRugged casing and baseplate/pedestal supportsystem provides flange-loading capability exceedingAPI 610 / ISO 13709 requirements without the use ofa bearing frame support.Not All Pumps are Designed for Low FlowsMany users throttle pumps to attain low flow rates, whichcreates bearing and seal issues. The traditional enclosedimpeller passageways would be too small to properlymanufacture at these low flow rates. Full Flange Rating Pressure CapabilityAll pumps designed to operate at two pole runningspeeds have casings designed for the full pressurecapability of a 300 RF flange.3700LF Low-Flow Solution - Fully API compliantThe 3700 LF semi-open radial vane Barske type impellereliminates these enclosed impeller limitations. The uniquecircular volute casing eliminates diffusers, thus reducingthe pump size, footprint and lifetime costs. Spiral-Wound Casing GasketCasing to cover joint sealed with a spiral-wound,controlled-compression gasket required by API 610.Provides positive sealing up to the maximum designpressure and temperature.Improved Bearing Environment Bearing frame fins provide optimum heat dissipation. Condition-monitoring sites allow easy and consistentmonitoring of temperature and vibration. Provisionfor instrumentation mounting per API 670 available.Optional Design for Solids Handling- Model 3703For over 19 years, ITT has offered a fully API compliantoptional design (Model 3703) that utilizes a traditionalstyle semi-open impeller - useful when you require a pumpwith high temperatures or pressures, yet need theimproved solids handling of an semi-open impeller.Examples of 3703 services are mine dewatering and PTAchemical plant services. The single stage Model 3703 hasinterchangeable parts with Model 3700.4Goulds 3700 Large oil sight glass allows viewing of the conditionand level of oil, critical for bearing life. Extra-large oil sump means cooler-running bearings. Proven channeled oil lubrication system ensuresflow-through of cooled oil to thrust and radial bearings. Standard dual oil rings, positively located, provide oilflow to channeled oil lubrication system and preventoil foaming.LOI ELVLE
