Features & Benefits
Goulds Water Technology G&L Pump Series 3642 - Residential, Commercial Close-Coupled Centrifugal Features and Benefits: Vertical or Horizontal mounting capabilities, Close-coupled, space saving design, Standard carbon/ceramic faced mechanical seal with BUNA elastomers, 300 series stainless steel components. Optional seals available, Enclosed impeller design for high efficiencies, Motor is a close-coupled design.Ball bearings carry all radial/axial thrust loads. Designed for continuous operation. G&L Pump Series 3742 - Residential, Commercial ½ to 3 HP Frame-Mounted Centrifugal Pumps Features and Benefits: Construction: Available in bronze-fitted (BF), all iron (AI), or all bronze (AB). Bronze-fitted means bronze impeller. Frame-Mounted Design: Flexibility of installation and driver arrangements. Back Pull-Out Design: Simplifies maintenance when used with spacer type coupling. Cast Iron Power Frame: Rigidly supported, grease-for-life ball bearing assembly. Impeller: Enclosed design for high efficiencies. Threaded directly on pump shaft. Stainless steel locknut on three phase models. Requires no clearance adjustments. Balanced for smooth operation. Mechanical Seal: Standard John Crane Type 6 with carbon versus ceramic faces, BUNA elastomers, and 18-8 stainless metal parts. Optional high temperature and chemical duty seals available. Motors: NEMA standard open drip-proof, totally enclosed fan cooled or explosion proof enclosures. Rugged ball bearing design for continuous duty under all operating conditions.
General Description
3642 / 3742 pump applications include water circulation; booster service; liquid transfer; spray systems; jockey pumps; OEM applications; and general water services. General applications traditionally requiring various materials such as all iron, bronze-fitted or all bronze construction
