3.7 Casing Design Pressure (1) Casing design pressure except for double casing or multi-stage pumps should be higher than the maximum discharge pressure (MDP), except that the thickness of the pump casing is to be suitable for the MDP plus allowances for head and speed increase. (2) Hence, the maximum discharge pressure (MDP) is decided according to the following formula: MDP (kgf/cm2G) = Shutoff head (D x Sp.Gr. + MaJt_ Buction preBBUre 10

(kgf/cm2G)

If the pump head curve has a peak point, the shutoff head should be replaced with a peak head. Further to the above, the maximum discharge pressure may be equal to setting pressure of a relief valve provided that the relief valve is equipped at the pump discharge. (3) When the MDP exceeds 1.1 times pump rated discharge pressure, it will affect potentially the design pressure of equipment and systems at down-stream of the pump. In this case, the design pressure of the subject equipment and systems should be adjusted accordingly.

3.8 Total Head of Vertical Sump Pumps For vertical sump pumps, the following points should be taken into account to avoid misunderstanding between Purchaser and Vendor:

(1) It should be clearly stated on the inquiry specification (i.e. data sheet), that the discharge pressure and total head is designated at the point of discharge nozzle. (2) When pumps are tested in performance at Vendor's shop and the discharge pressure is measured at the point of * in Fig. 9, the pump performance should be corrected accordingly. FORM A-G30.014

Bearing Material for Vertical Pumps

(1) Material for radial bearings of vertical pumps should be carbon, which has the strong recommendation from past experience. (2) For low temperature service such as liquid ammonia or liquid propane gas (LPG), this requirement is mandatory, (3) 3.10

For water service, cast iron, niresist or bronze is applicable, Insulation for Vertical Pumps

Vercial pumps for low temperature service are usually provided with cold insulation around their barrel to protect the pumps from being jacked up due to freezing. In this case, the designer should take care of baseplate size and position of anchor bolts to be properly fit with the insulation (Fig. 10).

ENGINEERING MANUALS DESIGN CONSIDERATIONS FOR CENTRIFUGAL PUMPS

TEM 4 1 4 1 E PAGE 9 OF 13 3.11

Equalizing Piping for Vertical Pumps

Vertical pumps handling saturated liquid such as LPG and liquid ammonia should be furnished with equalizing piping at pump suction in order to get ventilation. This piping should have enough size to vent gas released and should rise continuously to a suction vessel. The equalizing piping is preferably separated from flushing piping from/to mechanical seals. 3.12

Automatically Started Pumps

(1) A starting torque curve of automatically started pumps has a different shape from that of manually started pump as shown in Fig. 11. (2) The designer should clearly identify the pump which is automatically started and inform a motor manufacture of this fact. If necessary, the starting torque curve should be sent to the motor manufacturer. Remark: In Fig. 11, the cross point of the torque curves gives us an idea of operating speed.

®-DISCHARGE VALVE OPEN (AUTOMATIC) ©---DISCHARGE VALVE SHUT (MANUAL) Fig. 11 Pump Starting Torque Curve (3) It is recommended that output power rating of drivers should cover the power required by the automatically started pump at the end of curve. 3.13 Shaft Seals (1) Mechanical seals will be used for flammable or toxic service. API Standard 610 calls for use of the mechanical seals for all services. (2) Gland packings can' be used for services of cooling water, steam condensate or other water. (3) The mechanical seals, which are used for the service containing slurry, are externally flushed with clean liquid. (4) For high temperature services, the mechanical seals are usually provided with a cooler in a flushing line or they are of bellow type.

single

mechanical seal with quenching 2 -

under 0.4 kgf/cm G :

Double

mechanical seal (6) Recently a tandem or a double mechanical seal becomes popular in use for low temperature hydrocarbon. The double mechanical seal needs an expensive sealing system consisting a reservoir, pumps and coolers. (Refer to Attachment (4) in detail.) Non-seal pumps can be optionally replaced with such special application.

FEB. 10,89 Resonance Vibration of Large Vertical Pumps with Motor Speed

If a frame of large sized vertical pumps has an resonance in natural

frequency with Z x operating speed (2=1,2.......), such pumps do potentially encounter vibration. (2) During detailed design stage, the resonance frequency should be checked to be far from the revolutional speed and at the test it should be examined by hammering, etc. 3.16

Thrust Balancing and Shaft Sealing

(1) Thrust froce around an impeller with a balance holes will become different from that without balance holes as shown in Fig. 13. (2) When the impeller is provided with balance holes and suction pressure is higher than 15 to 20 barG, the thrust force loading impeller opening cannot be properly balanced, which results in overloading to the thrust bearing. Thus, in this case the impeller will not be furnished with the balance holes at all. (3) When the suction pressure of pumps is very close to liquid vapor pressure, flushing liquid, i.e. self liquid, in a stuffing box is possibly vaporized by heat generated at the part of matings of a mechanical seal provided that the box pressure is equal to the suction pressure. In this case, the impeller will not be furnished with the balance holes, either. (4) The box pressure, in such a.case that no balance hole is furnished, is nearly equal to pump discharge pressure. Flushing liquid to the mechanical seal will be circulated to "pump suction, which is called "Reverse Flushing" (API Plan No. 13).
