seepex Metering Pumps Receive NSF 61 Certification
seepex metering pumps are now certified to meet the NSF 61 standard for use in treating water and wastewater. seepex pumps are certified safe to use for sodium hypochlorite, ferric chloride, sodium bisulfate, potassium permanganate, sodium silicofluoride, calcium fluoride, polymers and most other chemicals commonly used in water and wastewater flocculation, clarification, sterilization and buffering.
The NSF Standard 61 for “Drinking Water System Components-Health Effects” is the ANSI Standard for drinking water system components. It is intended to minimize any negative effects on the health and safety of the public and the environment. The certification process required toxicity and leaching tests with actual pumps and components with the actual chemicals. All pump components that come in contact with pumped material must be traceable back to the mill, foundry or chemical plant producing the raw materials. Vendor certification requires periodic audits of the production facilities, actual parts and purchase records.
NSF International led the development of these American National Standards and is a global independent public health and environmental organization that provides standards development, product certification, testing, auditing, education and risk management services. This mark of distinction assures customers that seepex pumps are safe for use in drinking water processes and is a substantial move forward for seepex in the environmental industry.
More on the NSF 61 standard is available here.
ALPHA Chemical Metering Systems by seepex
Accurate, Less chemical consumption, Pulsation free, High quality components, All things flow
seepex’s new series of standard ALPHA chemical metering systems are designed for simple plug-and-play installations. Installation is as straightforward as connecting three pipes and plugging into a 115 Vac power source. The systems come in five standard skid configurations: simplex options (one pump, wall or floor mounted), duplex options (two pumps, wall or floor mounted), and triplex option (three pumps, floor mounted).
Included are NSF/ANSI Standard 61 certified progressive cavity metering pumps which offer several advantages for chemical metering due to the principle of the pumping elements. A metal rotor rotates inside a rubber stator, forming two cavities at the suction end of the stator. As one cavity closes, the other opens forming progressing cavities from one end of the stator to the other. The compression fit between the rotor and stator prevents siphoning and back flow. The pumps are self-priming, pulsation-free and will not vapor lock. No pulsation dampeners, back pressure valves, or check valves are needed.
ALPHA systems handle pressure ratings up to 175 psig and flow rate capabilities from 0.1 GPH up to 70 GPH. Turndown capabilities are 600:1. Regardless of the chemical source tank location, installation remains flexible due to suction lift capability of up to 35 feet. Complete skid assembly includes a mounted unit with pump(s) and gearmotor(s), control panel with controls for flow regulation, calibration column, relief valve, instrumentation and piping. Systems offer local or remote operation with H-O-A switch on NEMA 4X Control Panel with VFD as well as complete protection from overpressure. Control inputs/outputs also include clear power and pump running indication lights, flow command, running speed control, flow rate indication and fault alarms.
The ALPHA systems are for use in a variety chemical metering applications. Accurate, non-pulsating, and repeatable flow capability results in tighter control and chemical consumption reduction. All skid components are chemical resistant and will hold up in harsh environments. The systems safely deliver thin to highly viscous liquids and withstand corrosive and solid laden chemicals. Key chemicals handled include:
• Aluminum ammonium sulfate
• Aluminum Sodium Sulfate
• Aluminum sulfate
• Aqueous Ammonia
• Calcium carbonate
• Calcium chloride
• Calcium Fluoride
• Calcium hypochlorite
• Copper sulfate
• Ferric chloride
• Ferrous chloride
• Hydrated Lime (Calcium hydroxide)
• Magnesium hydroxide
• Magnesium sulfate
• Potassium permanganate
• Soda Ash (Sodium Carbonate)
• Sodium bisulfate
• Sodium fluoride
• Sodium hydroxide (Caustic)
• Sodium hypochlorite
• Sodium metabisulfite
• Sodium silicofluoride
• Sodium sulfite
• Sulfur dioxide
• Tricalcium phosphate
seepex’s Pre-engineered Chemical Metering Skid System wins Processing Magazine’s 2013 Breakthrough Product of the Year Award
The Breakthrough Products of the Year awards recognize products, technologies and services that made significant contributions in the process industries within the last year and are expected to impact the industry for years to come.
Introduced at WEFTEC in November of 2012, seepex Inc. now offers pre-engineered skid systems for use in a wide variety of liquid chemical dosing applications, primarily in the disinfection processes of water and wastewater treatment facilities. The systems are special compared to similar products because of the complete customization of chemical resistant components and materials per application, eliminating the valuable time and costs associated with engineering, procuring, assembling, and commissioning flow control systems. Systems are commissioned at the factory according to the application’s flow ranges and then calibrated according to the flow control loop. The skids hold up in harsh acidic and caustic chemical environments and can deliver mild to aggressive, thin to highly viscous liquids, as well as corrosive and solid laden chemicals with non-pulsating flow, and accurate and reliable metering.
Each unique system comes with all the components necessary for chemical dosing (including seepex progressive cavity pumps, calibration column, pressure gauge, pressure switches, dry run protection, and flow meters) packaged into a single unit with or without controls and framework. An integrated vector drive with automatic (4-20mA) or manual speed control also comes standard, eliminating the need for a local interface/control panel. The system handles pressure up to 350 psi, flow rates from 10mL/min to 100gph, and has turndown capability of 60:1. PC pumps do not have ball valves, therefore they are not prone to vapor lock and do not require back pressure valves or priming chambers.
Die Cast Lubricant Manufacturer Benefits from Progressive Cavity Pumps
seepex is deeply involved in the chemical industry. Although many processes seem obvious fits for a progressive cavity pump, others are a bit less common. Progressive cavity pumps (PCPs) are particularly well suited for chemical applications due to their valveless design, controllable flow and low pulsation. The term for this innovative use of PCPs in such applications has been coined “valveless flow control.”

seepex Solves Magnesium Hydroxide Problem with Innovative Smart Conveying Technology
A leading technology company engaged in the worldwide development, commercialization and application of state-of-the-art propriety technologies for air pollution control, process optimization and advanced engineering services tried to use several different kinds of pumps to get the job done, but in the end seepex BN range progressive cavity pumps complete with Smart Conveying Technology (SCT) proved most effective, reliable and economical, all while providing the easiest maintenance and longest service. The N range seepex progressive cavity pump is the most common seepex progressive cavity pump.
seepex Chemical Metering Pumps Save Water Treatment Plant Time and Money
For a water treatment plant in Norfolk, Va., a seepex hypochlorite pump turned out to be superior to previously used models because the pumps are reliable and service friendly, which means less downtime due to repairs. The pumps offer significant cost savings, up to $5,000 a year in repairs alone. The pumps can operate against high pressures without pulsation, will not vapor lock and are protected from dry run and overpressure to maximize the lifecycle costs of the pump.
