Chemical Feed Stations
Complete, ready-to-use, lightweight, easy to handle, and self-contained NSF-approved chemical feed stations with overflow basins allow you to dispense small amounts of liquids very accurately. Our custom designs allow us to add features such as molded pump shelves, polyethylene primary tank stands, custom design fittings, level sensors, dosing pumps, and other accessories to individualize any customer's needs. The tanks, catch basins, and other features of the chemical feed stations are constructed from high-density crosslink polyethylene or FDA-compliant linear polyethylene. We offer very simple stand-alone tanks with catch basins up to systems that include pumps, sensors, heaters, and many other accessories. Please contact us today with your specific needs so that we can design the best solution to your challenge.
Compact, Complete and Ready to Use
Assmannfeed stations allow you to handle small amounts of liquids and other chemicals without the handling costs and inconvenient disposal of steel drums.
- Lightweight, easy-to-handle.
- 35 gallons up to 500 gallons.
- Uniform wall thickness allows the entire surface to cure evenly for a strongertank.
- Air-cooled for a more uniform resin cure, reduced wall stress and improved shrinkage parameter for more consistent quality, greater structural integrity and longer life.
- Primary tanks are semi-translucent.
- Basins can holda minimum of 110% of the primary tank (Check local regulatory agencies for compliance in your area).
- 16” threaded lid with removable 6” air breather, open-top or hinged lids available.
- Easy-to-read volume markers.
- Polyethylene pump shelf supports most pumps and metering devices. Optional fiberglass shelves are available for pumps and metering devices totaling 25 pounds or more if required.
- Polyethylene tank stands, which may be stacked 2-high, will support the primary tank for gravity feed if required for an application. These can be placed inside the containment basin if required.

Choosing The Right Dosing/Metering Pump for Your Chemical Feed Station
Diaphragm metering pumps are best in applications where you need to pump clean, aggressive chemicals into high-pressure systems, and require very little maintenance. Whereas Peristaltic metering pumps work best when you have “dirty” fluids that contain trapped gases or particulate matter liquids that need to be pumped into lower pressure systems.
Diaphragm Pumps
Solenoid actuated (electronic) diaphragm metering pumps are the most economical option in applications for low-flow/low-pressure chemical-dosing applications.). They offer a repeatable dosing accuracy of +/-3 percent. They are normally provided with an onboard relief valve to prevent pump damage from over-pressurization. Powerful microprocessor technology guarantees dosing accuracy, while wall and base-mounting options, constant and proportional dosing, and analog and digital variants provide unrivaled choice. The use of premium materials such as PVDF and food-grade PTFE in the liquid end components gives our solenoid dosing pumps the flexibility to be used in multiple applications, as they have high resistance to a variety of aggressive chemicals including highly corrosive substances such as acids. With just a single moving part, these diaphragm pumps are virtually wear-free and require no lubrication of bearings or shafts, minimizing maintenance requirement and repair costs while offering excellent continuous-running characteristics.
Peristaltic Pumps
Peristaltic chemical metering pumps give users a unique advantage over diaphragm metering pumps as they can deliver at flow rates that remain constant right up to 100 psi and they eliminate the need for ancillary equipment while ensuring accurate, linear, and repeatable metering across all process conditions. This pump technology, simplistic in its design, is perfect for handling viscous and abrasive chemicals. Because the design features a rotor with shoes or rollers that squeeze the hose or tube and force the liquid to the discharge port, peristaltic pumps are able to run dry and do not have valves that can become clogged. Every model in this range of automatic dosing pumps is IP65 rated for dust tightness and resistance to water jets and includes premium-grade Santoprene and SekoBril tubing as standard, providing long life and exceptional chemical compatibility. A plethora of other tubing options are available for the safe pumping of aggressive fluids in the most severe applications. Outstanding dosing accuracy is achieved via intuitive analog and digital control along with high-precision stepper motors (certain models), while the user-friendly design means accessing, inspecting, and replacing peristaltic tubing is quick and easy.
