2 Introducting Deming 3020/3120 Series End-Suction Centrifugal Pumps Crane Deming offers an exciting, new design in end-suction centrifugal pumps for continuous operation in generate industrial, OEM and HVAC service. They come in framemounted (Models 3021 and 3121) and close coupled (Models 3022 and 3122) designs and in 30 sizes from 1 to 8. The new Series 3020/3120 pump features a hydraulically balanced, computerdesigned, enclosed and semi-enclosed impeller to ensure the highest hydraulic efficiency available in the pump industry. Maximum interchangeability of parts allows for reduced parts inventories. Other features include a rugged, one-piece casting for suction head and casing; back pull-out design for ease of maintenance; regreaseable bearings; and a two-year warranty against defects in materials and workmanship. Industrial and HVAC users like Series 3020/3120 end-suction pumps because they provide continuous service with essentially no maintenance. OEM users like them because of their reliability, low maintenance and compact design. More than a century of research, engineering and manufacturing experience stands behind your selection of a Deming end-suction centrifugal pump. It will prove to be a wise choice.

6 *Enclosed Impeller Design TYPICAL ARCHITECTS/ENGINEERS SPECIFICATIONS GENERAL:The contractor shall furnish and install as shown on the plans, (qty) Crane Deming (Horizontal Frame Mounted) (Close Coupled) series 3020/3120 Size ( ) Centrifugal pump(s) as herein specified. The pump(s) shall be rated for continuous service and of (All Iron), (St. Stl. fitted), (Bronze fitted) construction for the following operating conditions. Each pump shall be capable of delivering GPM of (Liquid) against feet total head. The following characteristics of the liquid to be pumped are: LIQUID HANDLED SPECIFIC GRAVITY TEMPERATURE VISCOSITY OF LIQUID AT PUMPING TEMPERATURE NPSHA MODEL 3021/3121 HORIZONTAL FRAME MOUNTED: The design requires a 4140 steel shaft sized for a maximum deflection of.002 at the seal faces with the pump running (at ) (under ) maximum load conditions. The bearings shall be (grease) (oil) lubricated having a 3 year minimum life (AFBMA B10) under the maximum load conditions and protected from outside contamination by oil seals. The shaft and bearings are to be encased in a cast iron ASTM-A48 Class 30 frame and the thrust bearing housing is to be of a micrometer adjustment design. The Model 3021/3121 pump and motor will be mounted on a common (fabricated steel with drip rim) (steel) baseplate. Pumps are to be coupled to the driver by means of an approved (spacer) (nonspacer) type coupling with an OSHA approved coupling guard. NOTE: Add any additional facts concerning the nature of the liquid or installation which might affect the pump construction, application or operation. MODEL 3022/3122 CLOSE COUPLED: The pump is to be coupled directly to a Nema JM Frame HP Phase Hertz Voltage RPM Enclosure motors. The adapter to the casing is to be one piece cast iron construction capable of mounting a John Crane Type 21 mechanical seal. The standard seal construction is carbon vs. ceramic faces, stainless steel hardware with buna elastomers: various other face materials and elastomers are available, depending on the medium being pumped. The maximum operating temperature is 2250 F. CONSTRUCTION DETAILS CASING:Casing shall be of close-grained ASTM-A48 Class 30 Cast Iron with a minimum tensile strength of 30,000 PSI. The casing shall be vertically split with centerline discharge and back pull-out design, capable of standing hydrostatic test pressures of 1-1/2 times maximum working pressure. All assembly points shall be of machine register fit to assure proper pump alignment. The casing shall also have a tapped and plugged drain connection available for any of the eight (8) rotatable casing discharge positions. CASING CONNECTION: The threaded and flanged casing nozzles shall conform to ANSI NPT and B16.l specifications with a minimum 125 PSI ratings, all flanged nozzle connections shall be standard flat face. CASING WEARING RINGS: Casing wearing rings of 316 st. stl. material for service and easily replaceable design shall be provided as standard both in front and rear of the impeller. IMPELLER: The impeller shall be of the (enclosed) (semi-enclosed) single suction type of (cast iron) (bronze) (316 stainless steel) both statically and hydraulically balanced for maximum efficiency and smooth operation. Holes shall be provided through the impeller hub to keep positive pressure on the mechanical seal and balance axial thrust loads. Impeller shall be positioned and securely locked to the shaft by use of a key, hex head impeller nut and washer. Models using 3121/3122 are of the enclosed impeller design, whereas Models 3021/3022 will be semi-enclosed impellers. IMPELLER WEARING RINGS (Optional): Impeller rings of 316 st. stl. material shall be securely mounted on the impeller hubs to provide for renewable clearances. Impeller wearing rings are available on enclosed impeller designs only. SHAFT SLEEVE: The sleeve shall be of the renewable type in 316 stainless steel and completely cover the shaft in the seal area. Sleeve shall be locked in place to prevent axial movement and sealed with a gasket between it and the impeller. CASING/SEAL (HOUSING) HEAD ADAPTER: The adapter shall be one piece integrally cast with the seal head to mount on either a close coupled 3M motor or the appropriate frame assembly. The design of this chamber shall have a machine register fit on both ends to maintain positive alignment from casing to (frame) (close-coupled motor). The design shall incorporate an open seal chamber to allow maximum flushing action at the mechanical seal faces. WARNING: Coupling guards must be used to avoid serious injury to operating personnel.
