Oil pumps
Oil pump conversion
The tables below give the following pump
conversions:
• Danfoss RS pumps to RSA pumps
• Danfoss RSL/MSL/MS/BFP pumps to BFP
service pumps
• Suntec pumps to BFP service pumps
• Eckerle pumps to BFP service pumps
• Delta pumps to BFP service pumps
Using Danfoss service pumps BFP 21 L3 and
BFP 21 R3 it is possible to maintain 90% of
existing small burners. In other cases it can
be difficult to find the correct Danfoss service
pump. The main purpose of the conversion
tables is to make the replacement of such
pumps easier.
The tables are compiled as follows:
• Column 1 always gives the pump type to
be replaced.
• Column 2 gives the code number of the
pump to be replaced.
Note: Where Eckerle pumps are
concerned, column 1 gives the old and
column 2 the new designation.
• Column 3 states whether the pump is for
1-pipe or 2-pipe operation.
Note: With the MS pump, the numbers
“1 + 2” are shown together because this
particular unit has automatic changeover.
Eckerle pumps have no suffixes.
• Column 5 gives the Danfoss pump type
able to replace the existing pump.
• Column 6 gives the corresponding Danfoss
code number.
• The last column, »Comments/accessories«,
refers to special characteristics and
features. Please note that in some cases
accessories are necessary.
