Service & support
Support that lasts
as long as the pump.
Selection advice before you buy, guidance during installation and genuine spares and servicing for years after. Talk to the people who built your pump.
01What we do
Services.
Selection & sizing
We size the pump from your chemical, concentration, flow and back-pressure, and choose the pump-head material to match.
Installation guidance
Recommended layouts for negative and positive suction, injection points, foot valves and anti-siphon protection.
Commissioning & calibration
Priming, stroke setting and flow verification with a calibration column so the plant starts at the correct dose.
Genuine spares
Diaphragms, valve balls, seals, O-rings, foot and injection valves, tubing and service kits for our pumps.
Repair & servicing
Pumps returned to our Chennai workshop are inspected, repaired with original parts and re-tested before dispatch.
Complete dosing systems
Tanks, agitators, pumps, piping and calibration columns engineered and tested as one unit.

03Installation good practice
Right first time.
Follow the installation drawings in each data sheet. These points cover most site issues.
Suction side
Keep suction lift within 1.5 m, use the foot valve with strainer, and keep the suction line short, straight and free of air pockets.
Discharge side
Fit the injection (anti-siphon) valve at the dosing point and support the delivery tubing so no load rests on the pump head.
Setting the dose
Start at full stroke, then reduce stroke length and speed to the required flow. Adjust stroke length only while the pump is running.
Verify & maintain
Check the actual flow with a calibration column, and clean valves and strainers at regular intervals.
04Troubleshooting
Quick checks.
If the problem continues, call our after-sales line on +91 89398 69648.
| Symptom | Likely cause | What to do |
|---|---|---|
| No output | Air lock in suction line, empty tank, foot valve clogged, or suction lift too high | Prime the pump, refill the tank, clean the foot valve and check the lift is within 1.5 m |
| Low or uneven flow | Stroke length or speed set too low, dirty valve balls or seats, choked strainer | Re-set stroke length and speed while running, clean valves and strainer, verify with a calibration column |
| Output higher than set | Siphoning because discharge pressure is lower than suction | Fit or service the injection (anti-siphon) valve |
| Leakage at the head | Loose head bolts, worn O-ring or diaphragm | Tighten evenly; replace the O-ring or diaphragm with a genuine service kit |
| Pump runs but is noisy | Loose mounting or pipe strain on the head | Secure the pump to its base and support the suction and delivery lines |
05FAQ
Frequently asked
questions.
What is the difference between electromagnetic and motor-driven pumps?
Electromagnetic (solenoid) pumps such as FE-A, FE-AA Auto Dose and FE-CD have no motor or gearbox. They use little power and are ideal for low flows up to about 20 LPH. Motor-driven pumps such as FE-M use a motor and worm gear for high-capacity, continuous duty, up to 500 LPH on the FE-M-58C.
How is the dosing rate adjusted?
On FE-A and FE-AA pumps, output is set by both stroke length and stroke speed, giving a 10:1 turn-down ratio. Stroke length should only be adjusted while the pump is running. FE-M pumps use a manual stroke length adjuster.
Which pump-head material should I choose?
PP and PVC suit most water-treatment chemicals such as hypochlorite and antiscalants. PTFE is used for aggressive acids and solvents, and SS-316 for chemicals that need a metallic head. Tell us the chemical and concentration and we will recommend the material.
Can the pump lift chemical from a tank below it?
Yes. Our electromagnetic pumps are designed for negative suction with up to 1.5 m lift when installed with the recommended foot valve. For viscous or gassing chemicals, a flooded (positive) suction layout is preferred.
Why is an injection (anti-siphon) valve needed?
It prevents chemical from siphoning into the line when the discharge pressure is low, and stops process fluid from flowing back to the pump. It is supplied as a standard accessory.
Do you supply complete dosing systems?
Yes. We build ready-to-connect dosing systems with a solution tank, agitator, single or duty / standby pumps, valves, piping and a calibration column, all tested before dispatch.
Are spares available for older pumps?
We stock diaphragms, valve balls, seals, O-rings, foot and injection valves for our pumps, and can service pumps at our Chennai workshop.
Where can I find the technical specifications?
Every model has its own data sheet on this website, with ratings, materials of construction and installation drawings, available to view online or download as a PDF.
