Pump BasicsWhat are we talking about • Our focus has been to educate and make our distributors aware of our MP Pumps, Inc. products, markets, and applications. • This webinar has come about from the feed back we have received from you our distributors. • Application Data • Pump Curves • Beyond the pumps • Trouble shooting • What’s new • Key terms and definitions
Pump Basics Application Data • Keys to accurately sizing and applying MP Pumps: • Gather as much data as possible • Asking the right questions • Doing the research that may be necessary • Using available tools • Pump curves • Hydraulic Institute handbook • Accurately apply the data given • But before we go any further…
Pump BasicsAsking the right questions • Start at the beginning • Flooded suction or lift condition • Flooded suction, fluid is above the pump. • Lift required, if so how many feet will the pump be required to lift? • Application fluid • What is the fluid we are pumping? • Temperature • Solids • Specific Gravity • Viscosity • Abrasive • Concentration
Pump BasicsAsking the right questions • Flow and head required • Pump speed • Drive requirements • Pedestal or PumPaK® • Electric motor/Engine/Hydraulic • Pay attention to frame designations – “T”, “TC”, “C”, or “JP” • Horsepower restrictions • Voltage/Hertz/Phase requirements • Enclosure requirements • Metallurgy • Cast Iron/Ductile Iron/SS/ Bronze/NiBrAl/Aluminum
Pump BasicsAsking the right questions • Mechanical seal requirements • Temperature • Chemical compatibility • Abrasive fluid • Single or double seal • Using the Pump Curves • Speed • Impeller Trims • Priming Lines • NPSH • Efficiency
Pump BasicsOther Key Considerations • Specific Gravity- effects the HP requirements required for the pump to obtain a given duty point • the ratio of the weight of a given volume of liquid to the same volume of pure water. Water is 8.3 lb./gal. • Weight per gal. of fluid/8.3 = Specific Gravity of fluid • Viscosity- the resistance to flow; may effect the flow, head, and efficiency for a given application • Begin considering viscosity correction at 200 ssu or 40 cst • Viscosity correction factors from Hydraulic Institute • Open vs. Closed impeller • Flanged vs. Threaded connections • Minimum flow- not less than 10% of BEP
Pump BasicsBeyond the pumps • Instrumentation • Can play a key role in quickly diagnosing pump performance issues • Pressure gages • Flow meters • Timed tank level readings • How long does it take to transfer the product • Temperature gages • Isolation valves
Pump BasicsTroubleshooting • Self-priming pump priming issues: • Was pump filled initially • Impeller to wear plate clearance • Check valves in the discharge line • Duty point beyond the lift capability of the pump • Direction of rotation • Clogged suction line • Air leaks in the suction side • If hose is used is it rated for suction use
Pump BasicsTroubleshooting • Mechanical seal failures • Did the pump run dry • Correct impeller to wear plate clearance sets the correct seal working height • Incorrect application for materials of construction • Abrasives • Selected materials correct for the chemical concentration • Percent of concentration • Temperature
Pump BasicsTroubleshooting • PumPaK® installation • Key concern is correct setting of impeller clearance • Number one reason for incorrect setting of the impeller clearance is that the shim material is removed prior to mounting the PumPaK® • Shim material provided in the PumPaK® from the factory • Shim material maintains the proper impeller clearance during assembly • Incorrect impeller clearance can lead to inadequate performance and shortened seal life
Pump BasicsName Plate Data • MP Pumps name plates contain the following information • Model #: 5 digit number (this is different than the description) 21381 • Serial # : combination of numbers and letters (i.e. 11A0678) • 11 Last two digits of the calendar year of manufacture • A Month code • 0678 678th pump manufactured in a given month
What are we talking about?MP Pump Abbreviations Pump model and size MP part # Any additional features Pump or PumPaK® 21339 FM8 PMP C: PED 5.0 ??? ??? ?? Pump material of construction Impeller diameter How the pump is driven
Pump BasicsWhat’s new… • Addition of “How to videos” • How to install a PumPaK® • How to replace a mechanical seal • How to set the clearance on a Flomax pumps • How to set the clearance properly on a HTO pump • FRX 75H – 1” Hose connections • Flomax 30/35 Stainless Steel pump is coming!
Webinar Series Continues • Coming in October 2012 we will be presenting our fifth webinar dedicated to MP Pumps hydraulically driven pumps • We will be discussing our hydraulically driven pumps, the different hydraulic motors offered, and keys to their correct application and operation • Check out our Hydraulic pump catalog on our website, www.mppumps.com
Pump BasicsKey Terms and Definitions • Flow- liquid volume capacity of a pump stated in gpm or gph • Head- measure of pressure expressed in feet. Indicates the height of a column of water being pumped, 1psi = 2.31 ft • Total head- for a specific system, is equal to the total discharge head minus the total suction head or plus the total suction lift • Atmospheric Pressure- 14.7 psi = 33.96 ft of water • Suction lift- Occurs when the liquid source is lower than the pump. Pumping action creates a partial vacuum and atmospheric pressure forces liquid up to the pump
Pump BasicsKey Terms and Definitions • NPSH- amount of pressure available to push the liquid into a pump. • NPSHa- available, must be higher than NPSHr • NPSHr- required, needed by the pump to perform properly • Cavitation- the rapid formation and collapse of vapor pockets into liquid; due to phase changes from liquid to vapor and back to liquid • Specific Gravity- the ratio of the weight of a given volume of liquid to the same volume of pure water. • Water is 8.3 lb./gal. • Viscosity- the thickness of a liquid affecting its ability to flow. • Stated in ssu, cst, or cps
