MODEL 72 SIMPLEX AND DUPLEX STRAINERS AND FILTERS are designed for
minimum pressure loss and easy basket accessibility. Cast alloy construction
provides both durability and economy. Duplex models include a tapered plug valve
with metal-to-metal seat for long life in rough service. Simple one-stroke valve
operation allows for continuous flow transfer from one side to the other without
interruptions. Duplex types range from 3/4 to 8 inches in pipe size, and simplex
up to 12 inches. Cast iron, cast steel, stainless steel and bronze models are
stocked in many sizes. Special units can also be manufactured in other alloys,
including Hastelloy "C", Carpenter 20, and Aluminum. Steam-jacketed and
polymer-resin coated models are also manufactured. Threaded N.P.T. and A.N.S.I.
flanged port units are standard. Butt-weld and socket weld ports are also
available. Models for fuel oil and flammable fluid service bear the
Underwriters Laboratories (U.L.) label.
Kraissl strainers are manufactured in accordance with international standard
ASTM F1199 and F1200. Fabricated strainers and filters in larger sizes up to 30
inch pipe size are also available. Units can also be furnished to meet Military,
Coast Guard, and other specifications where required. Special ports for strainer
back-wash and control sensor installations can be provided. Automatic duplex
valve actuators and controls are also available.
MODEL 72AA SERIES Transfer (or Diverter) Valves are used to cost effectively duplex two external pieces of flow equipment with the least amount of associated piping and space. Simple one-stroke valve operation allows for continuous transfer of flow without interruption. Sizes 3/4" through 8 inch are commonly available in cast iron, cast steel, and stainless steel. Internal valve plugs are normally provided in cast iron, stainless steel, or bronze. A broad range of screwed (NPT) port and flanged models including A.N.S.I. Class 125 and 150 through Class 1500 are typically stocked. Cast construction and tapered metal-to-metal valve plug and seat provide durability for long-life. Kraissl Transfer Valves have been accepted for many years in accordance with A.P.I. 614 and other standards for lubrication oil systems.
ROTARY POSITIVE DISPLACEMENT LIQUID PUMPS
MODEL 60 SERIES PUMPS are Underwriters Laboratories listed for
fuel oil service They incorporate an internal gear design which provides a wide
range of applications. The speed of operation is chosen based on the viscosity
and flow rate of the liquid at pumping temperature. These cast iron pumps are
found on many fuel oil burner installations. For No.1 through No.6 fuel oils,
our reduction belt-drive pump sets can be rearranged to increase or
decrease supply requirements simply by changing belts and pulleys only, without
changing pumps. For heavy oils with viscosities from 150 SSU to 8000 SSU and
above, our reduction drive pumps are suggested with pump speed of approximately
400 RPM. Direct drive pump sets are also available for light oils and fluids
where 1200 RPM, 1800 RPM, or other special fixed speeds are appropriate.
Standard models are rated for pressures up to 100 psig. Capacities range from
1/2 to 200 gpm with high suction characteristics. Port sizes include 3/8 to 2
ROTARY AIR PUMPS
MODEL 21 cast iron roller pumps and MODEL 25 cast iron
vane-type air pumps are available for both vacuum and low pressure air service.
Free displacement capacities range from 3/4 to 70 CFM, for vacuums to 28 inches
of mercury and pressures to 50 PSIG. Built in, positive lubrication system with
oil supply sump is included.
