Overview of the Chem-Tech Series 100 Mechanical Diaphragm Pumps
The Chem-Tech Series 100 Mechanical Diaphragm Chemical Metering Pumps are general-purpose metering pumps designed for reliable, economical chemical dosing without the need for electronic controls. Their mechanical diaphragm design delivers consistent output and long service life, making them a dependable choice for municipal water treatment, utilities, and industrial processes.
Series 100 pumps are well-suited for applications where:
Accurate, adjustable chemical dosing is required
System pressures are moderate to high
Simple operation and easy maintenance are priorities
These are general-purpose mechanical diaphragm pumps designed for reliable, everyday chemical metering.
How the Chem-Tech Series 100 Works
Mechanical Diaphragm Drive Design
The Series 100 uses a motor-driven mechanical diaphragm to convert rotary motion into controlled, repeatable diaphragm movement. This design isolates the drive components from the process fluid, improving durability and reducing wear on internal components.
The sealed drive mechanism provides:
Consistent stroke motion
Reduced vibration
Long service life under continuous duty
This mechanical approach is especially well-suited for applications where electronic complexity is unnecessary or undesirable.
Adjustable Feed Rate Control
Flow adjustment on the Series 100 mechanical diaphragm pump is accomplished through a manual feed rate control with a locking mechanism. This allows operators to set the desired output precisely and maintain that setting during operation.
Benefits include:
Simple calibration
Stable turndown capability
Repeatable dosing once locked in
Performance Range & Capabilities
Flow Range
The Chem-Tech Series 100 is optimized for low- to medium-flow chemical dosing applications.
Flow range: less than 3 GPD up to 30 GPD
(0.47 – 4.72 LPH, model dependent)
This makes the Series 100 ideal for applications where precise chemical feed rates are required rather than high-volume transfer.
Pressure Capability
One of the defining characteristics of the Series 100 is its ability to maintain accurate dosing at higher pressures.
Maximum discharge pressure: up to 100 PSI (7 bar)
This pressure capability allows the pump to operate effectively in systems with backpressure, long injection lines, or elevated discharge requirements.
Materials & Wetted-End Options
The Chem-Tech Series 100 Mechanical Diaphragm Pump is available with multiple material configurations to ensure compatibility with a wide range of treatment chemicals.
Pump Head Materials
Clear PVC
PVC
Polypropylene (PP)
316 Stainless Steel
Clear pump head options allow for visual confirmation of flow and valve operation.
Diaphragm & Check Valve Options
Diaphragm materials: CSPE, Viton, PTFE-faced CSPE-backed
Seat O-rings: PTFE, CSPE, Viton
Check valve balls: Ceramic, PTFE, 316 SS
These options allow the Chem-Tech Series 100 Mechanical Diaphragm Pumps to be configured for common water treatment chemicals, including sodium hypochlorite and other conditioning agents.
Typical Applications
Chem-Tech Series 100 pumps are general-purpose mechanical diaphragm metering pumps used for reliable chemical dosing across a wide range of water treatment and industrial systems, including:
Municipal water and wastewater treatment
Chlorination and standard disinfection systems
pH control and chemical conditioning
Industrial process water treatment
Utility and infrastructure dosing applications
Their consistent output and mechanical reliability make them suitable for both continuous and intermittent duty.
For applications involving off-gassing chemicals (such as sodium hypochlorite), a dedicated Chem-Tech Series 100 degassing version is available and recommended.

Frequently Asked Questions
Is the Chem-Tech Series 100 self-priming?
Yes. The Chem-Tech Series 100 mechanical diaphragm pumps are self-priming, which simplifies installation and startup in many chemical feed applications. Actual priming performance may vary based on suction lift, tubing configuration, and chemical properties.
What is the maximum viscosity the Chem-Tech Series 100 can handle?
The Chem-Tech Series 100 is designed to handle fluids with viscosities up to 300 CPS, depending on the chemical and system conditions. Higher viscosities may require adjustments to system design, suction conditions, or pump configuration.
Can the Series 100 be adjusted while the pump is running?
Yes. The Chem-Tech Series 100 can be adjusted while operating using the manual feed rate adjustment knob and locking lever. This allows operators to fine-tune output without shutting down the system, supporting accurate dosing with minimal disruption.
What power options are available for the Chem-Tech Series 100?
The Chem-Tech Series 100 is available in multiple electrical configurations, including 115 VAC / 60 Hz, 230 VAC / 50 Hz, and 230 VAC / 60 Hz. This range of power options allows the pump to be used in a variety of regional and industrial installations.
Does the Chem-Tech Series 100 require recalibration after adjustment or maintenance?
Yes. After changing the feed rate or performing maintenance, the Chem-Tech Series 100 should be recalibrated to ensure accurate dosing. Pump output can vary with adjustment settings, system pressure, and chemical properties, so recalibration helps maintain consistent performance.
Is the Chem-Tech Series 100 a general-purpose metering pump?
Yes. The Chem-Tech Series 100 is a general-purpose mechanical diaphragm metering pump designed for reliable, everyday chemical dosing in water treatment and industrial applications where simple operation, durability, and consistent output are required.
