500°F Seal Cooling Jacket
Extends maximum working temperature of the D51 up to 500°F or higher
with an appropriate customer provided external cooling fluid source
connected to the cooling jacket ports.
The cover casing of the D51 and D61 can be replaced with a self-priming
chamber to aid pump priming where lifting fluids from a sump or lower
elevation is necessary. In these applications, the self-priming version
lowers maintenance by helping to prevent the pump from running dry and
extending the life of the pump seals.
The D51 pumps are also available in a vertical flange mount configuration
for tank mounted designs and special applications.
