Four-piece bolt-on jacket for a double
diaphragm, 2-inch pneumatic pump. Typical applications for these types of jacketed pumps
include peroxide service heated with hot water in the range of 175 F (80 C). The
temperature of the heating medium must be less than the safe operating temperature of
diaphragm materials.

Centrifugal pumps often need to be heated, particularly
before start-ups if there is residual process in the pump casing. High process viscosity
is a major contributor to pump motor burn-out. The 8"x10"x13" pump shown
left is used to pump molten DMT. The ControHeat Bolt Jacket is heated with 150 psig (10.3
barg) steam at 366 F (185 C). |

Progressive cavity pumps are used
throughout the processing industry to transport viscous products. The pump shown right
pumps molten candy. The heating medium running through the ControHeat Bolt-On Jacket is
hot water at 200 F (93 C).

Molten sulfur generated by Sulfur Recovery Units
(SRU's) usually is pumped to a sulfur pit. To prevent buildups of dangerous gases in the
pits, sulfur plants often use large blowers to pull sweeping air across the pits. Sulfur
becomes entrained in the sweeping gas. As the gas goes through the blower some of the
sulfur drops out. The ControHeat Bolt-On Jacket prevents sulfur buildup on the blower
intake, impeller passages, and bearing journals. |
