Type of baseplate for horizontal pump
(OP)
Dear all
please guide me on selection "drain-rim" or "drain-pan" or "partial drain pan" BASEPLATE (requirement of API-610)
which key parameters should be considered in selection?
Thanks

RE: Type of baseplate for horizontal pump
- Where are you?
- Where is the Pump being installed?
- Where is the pump being manufactured?
- Does the Pump manufacturer offer a choice of Base Plates?
- What Base Plate is furnished as a standard (at no additional cost)?
- What is the added cost for the alternate Base Plates?
- What is the commodity being pumped?
- Is the installation indoors or outdoors?
- If outdoors is the area paved?
Sometimes its possible to do all the right things and still get bad results
RE: Type of baseplate for horizontal pump
pump will be manufactured acc to API-610 at vendor shop
- Where is the Pump being installed?
At petrochemical site
- Where is the pump being manufactured?
in shop
- Does the Pump manufacturer offer a choice of Base Plates?
- What Base Plate is furnished as a standard (at no additional cost)?
- What is the added cost for the alternate Base Plates?
yes, as i seen before,every manufacture prefered to construct baseplate with "drain pan" design. but according to API-610, purchaser can specify type of design.i want to know more about selection each other.
7.3.1 Single-piece drain-rim or drain-pan baseplates shall be furnished for horizontal pumps. The purchaser
shall specify the rim or pan type as follows:
a) drain rim surrounding the entire baseplate;
b) drain pan surrounding the entire baseplate;
c) partial drain pan that covers the entire width of the baseplate.
- What is the commodity being pumped?
Hydrocarbon (HC) liquid ,H2s=1780 ppm , CHLORIDE CONCENTRATION=121000 ppm
- Is the installation indoors or outdoors?
pump will be installed at outdoor
- If outdoors is the area paved?
Yes
RE: Type of baseplate for horizontal pump
When a pump processes a liquid where falling or accumulation poses a problem (corrosion or combustion), the base is them required to serve as a collector of incidental leakage.
The drip pan is preferable to the drain rim, because the latter may interfere with the leveling screws. A sloped center drain, either flat or dropped, will work, but the flat design is easier to grout.
Drip pan bases provide an extensive sloping drainage but most be designed and are difficult to fabricate.
Drain rim bases are usually easier to design and fabricate. The disadvantage with drain rim bases is that the areas where the leakage drops is generally flat and will accumulate some leakage.

RE: Type of baseplate for horizontal pump
Whatever you want it to collect, you need to make sure it's under that drip.
If you're only concerned with drips from the seal area, a partial / pan might be okay. If you also want to collect any oil leakage from the bearing housing, you probably want a full drip rim.
What is it that you're concerned about collecting?
