HHD Slurry Pumps
GIW's HHD Series Slurry Pumps feature high heads and high flows for dredging, pipeline booster stations and other severe duties.
The
slurry pumps in this series feature a proven shaft and bearing assembly
with spherical roller bearings and separate thrust bearings,
abrasion-resistant white irons, ductile irons and special alloys and
shell hydraulics designed with our predictive wear program to match
most any duty requirements.
Impeller
hydraulics are computer designed for high suction performance and large
solids passage. Other features include certified performance by: simple
construction, high efficiency and hydraulic testing in GIW's Hydraulic
Testing Laboratory.
These
slurry pumps are constructed as horizontal end suction centrifugal pumps to
give maximum resistance to solids while simplifying maintenance.
The
conventional single wall design transfers stress loads to non-wearing
side plates in high pressure applications.
Standard bearing assemblies feature a Built-In Bearing Isolator System.
The Built-In Bearing Isolator System, designed by GIW, is a labyrinth
seal built into the end cover plus the conventional V-ring flinger. It
extends the life of the bearing assembly, because it prevents contaminates from entering through the seal are.
The
shaft seal design of slurry pumps is controlled by the presence of
solids and the availability of purge water. The basic configuration for
this series is the stuffing box.
The Forward-Flush Stuffing Box is standard. Standard
lubrication is oil bath. Lube oil filters and coolers are not normally
required under 3,000 HP The extra measure of protection against
contamination should be considered above 3,000 HP.
Range
- Discharge diameters: 12 - 44 in. / 305 - 1118 mm
- Flows: 5,000 - 140,000 gpm / 1.136 - 31.800 m3/h
- TDH to 300 ft / 90 m
- Capabilities beyond 12,000 HP
Testing
Our performance curves are based on actual, full-size running tests on clear water in the largest slurry dredge pump test facility in the world. We guarantee our pump performance according to the Hydraulic Institute standards.
Hydrostatic tests can be carried out on all pumps at no additional charge in accordance with GIW ISO 9001 procedure 10.0001.01.00. These are performed at 1-1/2 times the operating pressure or 125 psi, whichever is greater.
