7 The supply tank and intake piping MUST be cleanedand flushed prior to pump installation and AND PIPINGAn improperly designed piping system or improper unitinstallation WILL significantly reduce pump performance andlife. BLACKMER recommends the following piping system layoutand unit installation. See Figure To minimize intake losses, locate the pump as close aspossible to the source of supply and a minimum of twofeet ( m) below the tank Intake piping and fittings MUST be at least as large indiameter as the pump intake connection. Inlet piping mustbe Use high strength Schedule 80 Minimize the number of intake line fittings (valves, elbows,etc.)

8 And piping turns or bends. The nearest fitting on theintake line must be at least 6 inches (152 mm) from thepump to permit access to the pump relief valve .5. Install an intake strainer 5 - 10 pipe diameters from thepump intake. The strainer must have a net open area of atleast four times the area of the intake pipe. Strainers mustbe cleaned regularly to avoid pump Intake and discharge piping MUST be free of all To facilitate piping expansion and contraction, expansionjoints must be placed 3 feet ( m) from the pump intakeand ALL piping and fittings MUST be properly supported toprevent any piping loads from being placed on the Install pressure gauges in the NPT ports provided in thepump casing to check pump performance at start The use a vapor return line will speed up delivery bypreventing back pressure from building up at the receivingtank and reducing pressure in the supply Keeping the liquefied gas systems full of liquid, even whenidle, will keep the O-rings from changing shape, shrinkingor super cooling.

9 Evaporation of liquefied gas leaves anabrasive powder on the surface which can cause wear tothe pump, meter, and MOUNTINGP ermanently mount the unit by securing the base plate withadequately sized anchor bolts to a level concrete floorfollowing recommendedindustry standards (SeeFigure 3). A solid foundationwill reduce system noise andvibration, and will improvepump performance. Refer toANSI/HI standards or asuitable pump handbook forinformation on typical pumpmounting and coupling alignmentafter pump and baseassembly is secured to 3 BOLTBASESTANDARDPIPEWASHERCOUPLING ALIGNMENTThe pump must be directly coupled to a gear, gear reducer,and/or driver with a flexible angular and parallel coupling alignment MUST bemaintained between the pump, gear reducer, motor, etc.

10 Inaccordance with manufacturer s instructions . See Figure To check for parallel alignment, the use of a dial indicator ispreferred. If a dial indicator is not available use a straightedge. Turn both shafts by hand, checking the readingthrough one complete revolution. Maximum offset must beless than .005" (125 microns).2. To check for angular alignment, insert a feeler gaugebetween the coupling halves. Check the spacing in 90degree increments around the coupling (four check points).Maximum variation must not exceed .005" (125 microns).Figure 4 - Alignment Check3 Storage TankFigure 2 UnionsBypass ValveGate or BallValvesIntake Connectionfor unloading tankcars or tank trucksDo no startpump unlessthis valve StorageTankDischargeStrainer4 OPERATION WITHOUT GUARDS INPLACE CAN CAUSE SERIOUSPERSONAL INJURY, MAJORPROPERTY DAMAGE OR cancause seriouspersonal AND OPERATION CRL BASE MOUNTED MOTOR DRIVEN PUMPSV-BELT DRIVEB lackmer also offers V-belt drive for CRL pumps.
