IX Series Metering Pumps are digitally controlled direct-drive diaphragm pumps. Years of experience in high-end motor technology result in extremely accurate and energy efficient metering pumps with high resolution. The IX Series meets today’s demand for automated chemical delivery in industries from water treatment to chemical process. Highly precise control offers a solution for a variety of dosing applications. Standard with several control methods, the IX Series pumps provide a solution to a variety of applications all in one pump.

The EJ Series provide precise chemical injection at an economical price. Universal voltage capability enables operation from 100 – 240VAC in virtually all countries. The EJ Series are compact, simple to operate and have outputs to 3.2 GPH (12.0 LPH) and a maximum pressure of 175 PSI (1.2 MPa).

EWN Series pumps have outputs to 6.7 GPH (25.2 L/h) and a maximum pressure of 290 PSI (20 bar). The high speed of operation results in high resolution chemical feed and long service life. Quiet and compact, the EWN pumps prime in seconds and hold prime reliably.

Outputs to 6.3 GPH and pressure capabilities to 150 PSI.

Simple to operate microprocessor control with a turndown ratio of 360:1

Dual bearing support ensures proper axial movement extending the life of the diaphragm.

Dual check valve assemblies in both suction and discharge fittings guarantees fast priming and reliable performance

High Performance & Versatile Design – The LK series has a discharge accuracy (repeatability) that is within ±2% FS. Reliability has been enhanced with the improvement in the linearity of the stroke and the discharge ratio of each stroke.

Drive- The heart of the LK is the dual-cam drive with a built-in worm gear type speed reducer. This compact & rigid mechanism, provides maximum wear resistance in continuous operation over long periods of time.

The LK-A, LK-B, and LK-C series pump are designed to be fit with IEC general-purpose, vertically mounted TEFC outdoor-use motors, providing different voltage and enclosure options, including VFD-ready and explosion-proof designs.

Liquid Ends
Drive from the gear reduction unit is directly transferred to the diaphragm. This design is
economical, yet retains a high degree of versatility. Liquid ends are available in PVC, PVDF and
316 SS for handling acids, bases, solvents, polymers and slurries.

Stroke Adjustment
Accurate and reliable stroke setting is accomplished with a micrometer dial of the springback stroke
adjustment mechanism. This lockable mechanism is adjustable from 10 to 100%.

Drive
The LK utilizes a dual-cam system drive with a built-in worm gear type speed reducer. The
aluminum bronze worm gear and the tapered roller bearing provide efficient transmission of
motor power to the pump. This compact and rigid mechanism provides maximum wear resistance in
continuous operation over long periods of time.

Motors
All of the standard models employ totally enclosed fan-cooled motors which are vertically mounted
to save space. A variety of motor options are available, including explosion-proof and DC variable
speed motors for external control by a 4-20 mA input signal.

Equipped with rugged, machined PVC or molded GFRPP liquid ends and spring loaded stainless steel valve balls, the HV series is designed for superior valve action and performance. Rated to 20,000 cps*, the HV series is available in feed ranges from 2.3 GPH to 8 GPH and pressures up to 73 PSI. Sophisticated design and backed with the industry’s only full 2-year warranty, the EH-HV series is the perfect solution for high viscosity feed applications. *Tested with 20,000 cps polymer verified with a Brookfield viscometer, Model LVF at 25°C, #4 spindle at 12rpm.

Specifically designed to accurately feed high viscosity chemicals.

Available in feed ranges from 2.3 GPH to 8 GPH and pressures up to 73 PSI.

Up to 240 strokes per minute results in high resolution chemical feed, reduced pulsation and improved mixing

Stainless Steel or Hastelloy C276 springs help quickly close the valve balls against the PCTFE seats, increasing the valve action with high viscosity polymers.
Liquid end, drive and electronics are modular, enabling economical repair or replacement of parts. The control module can easily be mounted in a remote location
PTFE laminate over EPDM is molded onto a solid core. A retainer plate is engineered to minimize flow rate changes as pressure varies.
