SPECIFICATIONS
1: SCOPE
To define the requirements for centrifugal pumps of the horizontal or in-line type. This standard, together with driver specifications, covers the requirements for design of the centrifugal pump.
2: GENERAL REQUIREMENTS
2.1 Pumps shall be Durco Mark III design as manufactured by Flowserve Corporation / The Duriron Company, Dayton Ohio.
2.2 Specific performance characteristics of the fluid are to be provided by customer. Vendor should be able to plot specific performance curves based on the specific properties of the fluid pumped.
2.3 Assemblies shall be furnished complete with pump, driver, coupling, and OSHA guard, mounted on a common baseplate with all required auxiliaries.
2.4 Coupling shall be a spacer type coupling of customer preference. Coupling guards shall be yellow in color. Polycarbonate "splash guards" shall be an option to prevent fluid spray from a malfunctioning seal.
2.5 Mechanical seal is to be installed by vendor and hydrostatically tested with water or air for a minimum of five minutes to test for any leakage prior to shipment.
2.6 Impeller shall be reverse vane design. The primary wear surface shall be the rear cover. No wear rings shall be required.
2.7 Impeller clearance shall be set to the rear cover by a micrometer dial adjustment located externally at the bearing housing.
2.8 Impellers shall be threaded to the shaft. Impellers are to be dynamically balanced at 3500 RPM to a quality grade of G6.
2.9 Metallurgy shall be of the most recent ASTM 744 specifications and conform to the chemical and mechanical requirements of ASTM 744 specifications.
2.10 Rear cover shall be available in a choice of five styles. Both oversized and standard bore sizes shall have an option for flow modifier (speed bump) arrangements.
2.11 Bearings shall be oil bath type with a reflective sight glass for level indication. Oil Seals shall be double lip both inboard and outboard. Optional bearing isolators shall be available.
2.12 Bearings shall be single row radial and double row thrust. Bearings shall have less than .001" of endplay.
2.12 Baseplate shall be of carbon steel, polycrete, or stainless steel material. Dimensions shall conform to ANSI B73.1-M1991 standard.
2.13 Assembly to be laser aligned to .005" Maximum. Motor centering nuts shall be used to allow for adequate clearance around motor fasteners. Motor adjusters shall be available as an option.
2.14 Motor driver horsepower rating shall be sized for run-out at the maximum required for the bid impeller. Motor enclosure shall be EPAct compliant with the Energy Policy Act of 1992. The efficiency levels to be met are those in NEMA MG1-1993.
2.15 Pump shall be identified by a stainless steel equipment tag. The tag shall have pump model and size, customer equipment number, serial number, capacity, head, RPM, materials of construction, and year of manufacture.
3: SPECIFIC REQUIREMENTS
3.1 Mechanical seal is to be of customer preference. Materials shall be selected depending on the application, seal manufacturers recommendation, and customer preferences. Both single and double seals shall be accommodated. Stuffing box shall be specified as either standard or oversize bore, with or without flow modifiers.
3.2 If required, Single seal shall be equipped with a by-pass-flush arrangement leading from the pump discharge to the appropriate connection on the stuffing box. The by-pass-flush shall be constructed of Teflon tubing with a stainless steel shroud. All fitting shall be stainless steel construction or higher alloy if required.
3.3 If required, mechanical seal tanks shall be mounted on a permanent fixture attached to the baseplate. Seal tank shall be of 2-gallon minimum size. Tank shall be mounted a minimum of 18" above the centerline of the pump.
This specification has been provided by The Pump Company and is offered for use by customers. When used in conjunction with proper sizing and application knowledge should provide a standard for customer pump requirements. We trust that you will modify this to meet your exact requirements.
SPECIFICATION FOR SUBMERSIBLE PUMPS
The tables below will assist you in the selection of the correct water pump for your needs. Note: Many customers tell us they underestimated their needs and wish they had bought a larger pump. For this reason, we recommend the selection of the pump one size higher than the minimum shown by the table.
We have never had a customer who whished they purchased a smaller pump!
FOUNTAIN PUMPS
For small table top fountain making the Rio pumps 50-600, ViaAqua 80-480 and the Fountain Pro 65-300 are most often used. You will want to consider the total height that the pump will need to pump to on the fountain. You will want to choose a pump that has a max head higher than the height you need to pump to. For example: a fountain that has water rising 2 foot would take a fountain pump that has a 2.5 foot or higher max head. If you do not use a pump with a max head higher than the level you wish to pump to then the water will barely trickle out. For more information on the construction of table top fountains please review Fountain Making Advice and Consultation.Larger indoor or outdoor fountains should consider a pump with a max head at least a foot or two higher than the height they will pump to.
POND PUMPS
There are many pond pumps available for all size ponds. From the smallest container watergarden to a 10,000 gallon pond, we have or can get the pond pump you need. Pond circulation should be 2 x 3 times volume of small ponds. Larger ponds should have circulation as close to total volume as possible. You will want to consider the total size of your pond in gallons. Length x width x average depth x 7.5 should give you a close estimate on the number of gallons your pond contains.
When you look for a pond pump, please choose only those that indicate a three prong heavy duty cord for outdoor use.
AQUARIUM PUMP
To assess your aquarium needs you should consider an aquarium pump that circulates 4 times tank volume for freshwater aquariums and 5 times for salt water aquariums. The use of filters or when raising water up from a well or sump more than 1 foot will reduce the total GPH flow and should be considered.
HYDROPONICS PUMPS
Our most popular selling water pumps for small home hydroponics systems are the Rio 600 and ViaAqua 360 and 480 pumps. Larger systems will require additional power and larger water pumps should be selected.
