AquFlow 4000 - Diaphragm Metering Pump
3530GPH + 3500 PSI + Highly Accurate
Not many pump manufacturers can boast a range of flows that start at fractional GPH and go up to 3,500 GPH. The Series 4000 diaphragm metering pumps come at the top end of this impressive pump line. Built like a battle tank, this dosing diaphragm pump is made to withstand the most brutal working conditions one can expect a pump to perform in. It balances size and boldness with precision delivering flow consistence with less than 1% variation.
Like all other AquFlow chemical dosing pumps, this also complies with API 675 requirements. It retains all the most popular and proven design elements present in other smaller AquFlow series: a hydraulically balanced diaphragm, wear parts that all work under lubricating hydraulic oil to minimize wear and a modular design that is easy to operate, maintain and rework.
Corrosion resistance is not compromised with the liquid end available in chemical resistant materials such as 316 Stainless Steel, Alloy 20, Hastelloy C, PVC and PVDF. The metered pump also uses a disc valve which affords a larger opening to allow more viscous and some solids if needed.

Capacity Control Options
- Dual Axis with both stroke length and stroke speed adjustable.
Stroke Length Controls
- Manual: Standard on all pumps.
- Electric: Electric stepper motor. Capable of 4-20mA input.

Tungsten Carbide Valve Balls
- For abrasive liquids.
Leak Detection Options:
- There are two types of leak detection options available with AquFlow pumps.
- Conductivity probe between 2 diaphragms to sense any break or rupture.
- Uses a vacuum switch between 2 diaphragms to sense any rupture or failure.
