Cooling Circulation Pumps and Installation

Specifications: New pumps are necessary for the Industrial Process Cooling circulation loops which draw glycol from the FERF main glycol buffer tanks and distribute them to downstream RDT&E applications. The new pumps shall be supplied with sheet metal protective covers against rain, debris and snow, which are painted white to avoid excessive heating. The Vendor shall provide equipment and services to meet the following specifications: A. Low Temperature Pumps Vendor is to quote supply of three (3) low temperature pumps. Vendor will install two on the low temperature glycol loop at the FERF and supply one to CRREL as a SPARE. The Low Temperature Pumps shall meet the following specifications: Rated to operate with a glycol/water mixture of at least 60% Dow Norkool SLH and 40% water. All seals, fittings, components and specifications must be based on 60/40 Dow Norkool SLH / water. Size: 2.5x3-10. This is a requirement for a 2.5-inch discharge, 3-inch suction, and CP size of 36. Must be for use with ANSI class 150 mating flanges. Flanges must be supplied by vendor. GPM rating: 282 GPM rating or better. Head rating: 69-FT TDH @ 282 GPM with 60/40 Dow Norkool SLH. Motor rating: 7.5 horsepower, 3/60/208-230/460 VOLT, 1750 RPM. Pump material: 316L stainless steel throughout. Seals: 10K126 SIL-Carbide EPR throughout. Frame: Stainless steel support frame. Temperature rating: -45F minimum to 120F maximum. B. Medium Temperature Pumps (Option). Vendor shall quote supply of four (4) medium temperature pumps. The vendor shall install all four (4) pumps, with two (2) each on the hot temperature glycol and medium temperature glycol loops respectively. The medium temperature pumps must meet the following specifications: Rated to operate with a glycol/water mixture of at least 60% Dow Norkool SLH and 40% water. All seals, fittings, components and specifications must be based on 60/40 Dow Norkool SLH / water. Size: 2.5x3-10. This is a requirement for a 2.5-inch discharge, 3-inch suction, and CP size of 36. Must be for use with ANSI class 150 mating flanges. Flanges must be supplied by vendor. GPM rating: 282 GPM rating or better. Head rating: 69-FT TDH @ 282 GPM with 60/40 Dow Norkool SLH. Motor rating: 7.5 horsepower, 3/60/208-230/460 VOLT, 1750 RPM. Pump material: 316L stainless steel throughout. Seals: 10K126 SIL-Carbide EPR throughout. Frame: Stainless steel support frame. Temperature rating: -15F minimum to 120F maximum. C. Ancillary Equipment Supply Electrical Supply: Vendor is to supply two (2) electrical disconnects with an option for an additional four (4) electrical disconnects, one for each unit to be installed. Each electrical disconnect will re-use the existing feeder cables. D. Cover Supply: Vendor is to supply two (2) framed steel boxes, with an option for four (4) framed steel boxes for protecting the pumps from the elements. These boxes will mount to the concrete pad or to the frame. They will provide at least one foot of standoff from all components of the pump. They will have holes, sealed at install, for the inlet and outlet pipes and the electrical supply. They will have at least three removable sides (top and two other sides, depending on configuration) which are connected with at least four (4) quick release latches each. The framed steel boxes shall be painted highly reflective white in outdoor duty, rust-resistant metal paint (two layers) with a primer layer below. E. Suction and Discharge Fittings: Vendor will supply new suction and discharge fittings, up to two feet in length each (flexible, metal woven jacket) to connect to existing piping. These will match ANSI 150 rated piping and be rated down to -45F. Vendor will supply three (3) with an option for an additional four (4), up to a total of seven (7); fittings may be multi-part depending on manufacturer but should be supplied one each complete with all parts necessary to work in this application and specified length. F. Installation. Vendor shall install six (6) pumps, two (2) being low temperature pumps and optionally, an additional four (4) medium temperature pumps. These pumps are installed in parallel in three (3) loops, the high temperature, medium temperature, and low temperature loops. The medium and high temperature loops are the process glycol loops for the optional CLIN. The medium temperature pumps will be used in the HT and MT loops and the low temperature pumps in the LT loop. Vendor will conduct a site survey before ordering fittings and will fabricate supports and framed steel boxes according to site conditions for successful installation of the pumps.
