How to obtain information about an existing MDM pump
To provide you with a spares quotation or other
information about an existing product manufactured by MDM Pumps Ltd,
we need to know the serial number. (Without the serial number, the
information we can provide is very limited). It is stamped in two
1) On the top of the pump, between the clamp ring and the motor. Every
pump has a serial number. At first glance it may appear that your pump
does not have one, but if you look carefully you will find it. Sometimes a
pump has been disassembled and then rebuilt with the number on the side or
on the bottom.
2) On the standard MDM nameplate, located on the motor or the cowl.
If the serial number on the cowl is different from
that on the pump itself, then the number on the pump will be the most
reliable, since the cowl may have been taken from another pump.
The serial number is typically of the form:
‘yyXpp’ is the MDM reference number for the
order, where ‘yy’ is the last two digits of the year of manufacture
(e.g. ‘98’ for 1998), ‘X’ is a capital letter and ‘pp’ are two
‘An’ is the pump sequence number (ie A1 to
A9) for that order.
For example, if an order was placed in 1998 for
three pumps, then the MDM order reference number might be something like
98Q27, and the pump serial numbers would be 98Q27-A1, 98Q27-A2 and
