SEEPEX Introduces: Intelligent Metering Pump

The programmable, precise and pulsation-free Intelligent Metering Pump (IMP) design is now available from SEEPEX.


SEEPEX’s MD metering/dosing progressive cavity pump line has been a staple of SEEPEX product offerings for decades. In an effort to continually improve on what is being offered, SEEPEX is proud to announce the Intelligent Metering Pump (IMP).

The new IMP design incorporates an Electronic Programming Module (EPM) memory chip on which parameters can be pre-configured. This makes replacement of a drive simple, quick and accurate. Simply insert the EPM chip from a previous drive into the new one for no downtime between stop and startups. A drive reset to factory default or customer settings takes no time at all. When the EPM equipped drive is used on a line containing multiple drives with identical setup, programming the entire line takes just minutes.

Each unit has a keypad on the controller lid equipped with operator elements for H-O-A selection, manual speed control, display of pump speed/RPM or flow, fault indication and the ability to change factory settings. Various accessories can easily be connected to the drive via the control terminals on the terminal strip inside the controller. A control module is also available as an option but it isn’t needed when accessories are wired directly to the terminal strip.

“At first glance this is just a metering pump with a VFD, but the IMP is different,” states SEEPEX Inc. Marketing Manager, Daniel Lakovic. “The new design is up to 30% lighter and provides better performance with no starting issues. The largest MD pumps can operate over 18 hours at 60:1 performance without overheating. The vertical fins help with cooling.”

The IMP design is available for SEEPEX MD metering and BW1 and BW2 wobble pump sizes and compliments SEEPEX’s comprehensive line of pre-engineered chemical metering systems. SEEPEX chemical metering systems are for simple plug and play installation.

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
• Bentonite
• Calcium carbonate
• Calcium chloride
• Calcium Fluoride
• Calcium hypochlorite
• Copper sulfate
• Ferric chloride

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.
