DI Water Flushed Pumps are for gas turbine inlet cooling.

Press Release Summary:

Gas Turbine Inlet Cooling deionized water pumps have ported inlet manifold that permits external flushing between low and high pressure seals. Block-style K models feature forged 316 SSL head that provides close grain structure and fatigue resistance against aggressive DI water, while C models are available with 316 SS cast head. All models include chrome-moly forged crankshaft, high-strength connecting rods, and concentric, high-density, polished, solid ceramic plungers.

Original Press Release:

D.I. Water Flushed Pumps for Gas Turbine Inlet Cooling

CAT PUMPS introduces the Gas Turbine Inlet Cooling D.I. water flushed pumps. Both cast manifold and block-style manifold pumps feature a special ported inlet manifold that permits external flushing between the Lo-Pressure and Hi-Pressure Seals. This patent pending application design greatly enhances seal life when pumping the low-lubricity DI water required for this gas turbine fogging application. The special seal flushing extends the seal life beyond the CAT PUMP historic seal longevity. The Stainless steel offers greater resistance to ion pull from the DI water maintaining the purity of the DI water. CAT PUMPS is the exclusive manufacturer of gas turbine inlet cooling DI water flushed pumps.

CAT PUMPS "K" block-style models feature a head machined from forged 316 SSL providing close grain structure and enhanced fatigue resistance against the
attack of aggressive DI water.

The "C" models are available with the 316SS cast
head. The special porting in the both cast and block-
style inlet manifolds permits the flush between the Lo-
Pressure and Hi-Pressure Seals, but also allows for any
leaking as the Seals begin to wear to be picked up by the
circulating liquid, avoiding external leaks and assuring a
safe work environment.

These flushed pumps are designed for intense, continuous-duty gas turbine DI water fogging/misting application. All models offer a near maintenance-free operation, energy-efficiency and long-life.

CAT PUMPS Long Life Features
o the concentric, high-density, polished, solid ceramic plungers and the specially formulated Hi- Pressure Seals offer unmatched wet-end performance life
o chrome-moly forged crankshaft and the special high-strength connecting rods assure exceptional drive-end performance.
