Pumps by Material:
Aluminum Pumps
ALUMINUM is a non-ferrous metal, very lightweight, approximately
one-third as much as steel. Aluminum exhibits excellent
atmospheric corrosion resistance, but can be very reactive with
other metals.
Aluminum Cast Iron Fitted
Brass
The term used for alloys of copper and zinc in a solid solution
is called brass. It is more than 50% copper and from 5 to 20%
zinc. Brass comes with good strength. It has excellent high
temperature ductility and reasonable cold ductility. Brass has
also good conductivity and excellent corrosion resistance. Since
it also has good bearing properties and low magnetic
permeability, it is a ideal material for construction of pumps.
Bronze Pumps
Bronze is the term used for alloys of copper and tin. Sometimes,
bronze is also found with other elements such as phosphorus,
manganese, aluminum, or silicon. It is strong and tough, and has
wide range of uses in industry. Bronze pumps are commonly
specified for use on seawater, hot water and certain chemicals.
Sintered bronze is a porous material, which can be impregnated
with oil, graphite or PTFE. It is not suitable for heavily
loaded applications but is of great use where lubrication is
inconvenient.
Cast Iron Pumps
Cast Iron (normally close grained SG irons) are a popular choice
for castings for general purpose pumps handling water, solvents
and caustic solutions at low temperature. Impellers can be in
cast iron or bronze. Cast grey iron is an alloy of iron, carbon
and silicon; easily cast; good pressure tightness in the as-cast
condition. Gray iron has excellent dampening properties and is
easily machined. It is standard material for general purpose
pumps. Gray iron has corrosion resistance that is better than
steel in certain environments.
Cast Iron Bronze Fitted Pumps
Gray iron has excellent dampening properties and is easily
machined. It is standard material for general purpose pump
casings. Gray iron has corrosion resistance that is better than
steel in certain environments. If the liquid handled is clean
water with very little sand or silt, bronze generally offers the
most cost effective solution. Bronze does not rust, is easy to
cast and machine and generally offer superior surface finish of
the waterways leading to efficiency gain.
Plastic Pumps
In plastic pumps all wetted parts are plastic material. Shaft,
pedestals and other non-wetted parts may be in metal or other
appropriate material. Plastic pumps are designed to move fluids
that would corrode or damage other types of pumps. They provide
broad chemical resistance and are less costly and lighter in
weight than metal pumps. Disadvantages of plastic pumps include
limited pressure ratings, reduced impact resistance, and
narrower temperature ranges. Some plastic pumps are designed to
move abrasive materials, acids, adhesives, chemicals, coolants,
hazardous materials, lubricants. Other devices are rated for
combustible, corrosive, high viscosity, or high temperature
media. Plastic pumps are also used to move gasoline, diesel
fuel, and oil; ground water, potable water, salt water, and
wastewater; sewage, sludge, slurry and ash slurry; gas and air;
powders, solids, and rendering wastes; and a variety of liquids
and liquids with solids.
Plastic Fitted Pumps
Stainless Steel 304 Pumps
304 Stainless Steel is the standard "18/8" stainless; it is the
most versatile and most widely used stainless steel, available
in a wider range of products, forms and finishes than any other.
The 304 stainless steel is the grade dominant in the manufacture
of drawn stainless parts. It is not suitable for seawater
Stainless Steel 316 Pumps
316 STAINLESS STEEL is an alloy of iron, carbon, nickel, and
chromium. A nonmagnetic stainless steel with more ductility than
304 SS. Austenitic in structure, 316 stainless steel has very
good corrosion resistance to a wide range of environments, is
not susceptible to stress corrosion cracking and is not affected
by heat treatment. Suitable for sea water pumping
Stainless Steel 304 Plastic Fitted
