Panner would love to invite you to join us for a plant tour of one of the Grundfos facilities.  Through acquisitions and their commitment to developing new products, Grundfos may be the fastest growing pump company in the world right now.  Their legacy brands include; Peerless Pump, Yeomans-Chicago Pump, Paco Pump, and Enaqua UV.  Grundfos is opening up the former Yeomans-Chicago plant for an open house on Wednesday, June 3rd from 10 am to 3pm. The plant location is 3905 Enterprise Ct, Aurora, IL 60504.   We'd love to have you as our guest.  For more information or to RSVP, simply leave your name in the comment section below, with the number of people who will be coming with you in parentheses.  We will follow up with you with complete details of the event.

Product Announcement: Type 578 Lug Style Butterfly Valve from GF

Georg Fischer has expanded it's butterfly valve product line to include the new Type 578 plastic-bodied lug-style valve. This valve incorporates many of the industry-tested design features that our butterfly valves are known for:

1. The double eccentric disk design disengages the disk from the seal while the valve is opening and closing, resulting in reduced component wear and decreased required operating torque.

• Reduces required operating torque by approximately 50%

2. The glass-filled polypropylene outer housing provides UV and chemical resistance while increasing impact strength.

3. The truly non-wetted 316 stainless steel shaft is protected by a precision bushing assembly featuring a redundant o-ring design.

Features

• Size: 2”–12”
• Body: Glass filled PP with overmolded SS316 lugs
• ANSI 150 bolt pattern
• Materials: PVC, CPVC, PP, ABS and PVDF
• Stem: 316 stainless steel
• Seal: EPDM or FPM; PTFE seals available upon request
• Operation: Bare shaft, lever, gear
• Actuation: Electric and pneumatic

Chemical Feed Pumps: Mounting Flexibility

Chemical feed pumps are the key component of many industrial and utility processes. These include:

• Cooling tower water treatment
• Boiler water management
• Water and wastewater disinfection
• Process chemical addition
• Cleaning chemical addition

These pumps are best applied along with ancillary items such as back pressure valves, calibration columns and pulsation dampeners to improve their operation or help control a treatment system.  Because of this, the chemfeed system can take up a large footprint in areas where space is at a premium. 

Pumps that give you mounting flexibility are important to optimize your use of space.  Pump manufacturers are introducing modular mounting designs that allow you to directly wall-mount their product.  With that configuration you can design an entire system like that shown below. 

We have both "standard" systems, and the capability to custom make systems to fit your unique space.  To learn more about how to maximize your floor space by vertically integrating your chemfeed systems, contact Steve @ 815-412-5683, or send an email to shapiro@panner.com

Eductor Mixing Systems

Process mixing within tanks is typically done using rotating blade electric mixers.  An alternative to this uses a recirculation pump with eductors.  In certain applications, eductors are a more appropriate method to mix tanks. 

The venturi effect creates a low pressure zone within a nozzle when flow cross-section is reduced. This low pressure area is used to draw surrounding fluid into the nozzle for a mixing effect.  Eductor nozzles    are installed on a manifold within a tank and connected to an external (or internal) circulation pump.  The venturi effect typically induces the addition of four gallons of liquid to every one gallon of pressurized liquid that flows from the pump. 

Rather than using a rotating mixer with blades, a pump and eductor system can be used to mix liquids in odd-sized tanks. Another advantage of educators is their availability in a variety of thermoplastic materials so they can be used with corrosive liquids.  Eductors are available in polypropylene, CPVC or  PVDF.  They can also be sourced in stainless steel or iron.

Recirculation manifolds are also a convenient location for chemical injection ports.  So if you are adding chemicals  to an existing tank you can inject and mix them easily.   Another advantage of eductor mixing is that the incorporation of 3-way valves in the recirculation system allows you to pump the fluid to a remote destination after the mixing is complete.

Eductors are inexpensive and require little maintenance compared to mechanical mixers.  This is especially valuable in applications requiring special corrosion resistant materials.
