There are a lot of chemical metering pumps that you can easily plug into a 110-volt socket. But what if you don`t have electricity and solar power is not practical? Furthermore, without on-the-spot labor, who is going to switch an electrical pump on and off and adjust the feed rate?
Enter the Wheel-Treater, a device that`s entirely powered by the flow of water, usually a small portion of the total flow.
In addition to being completely water powered, the Wheel-Treater is also responsive to changing water flows. This means that when the water stops flowing, the treatment stops. The chemical feed rate will follow varying water flow rates thereby increasing accuracy, eliminating waste and lowering treatment and labor costs.
Waterwheels have been used for thousands of years, but new runner and cup designs have evolved. Since the Wheel-Treater is designed to operate at relatively slow speeds, the runner design is simple and low maintenance. Since its original design, the Wheel-Treater has evolved to maximize torque, foot-pounds of power and hydraulic efficiency. Additionally, all models have large carrying handles and can be moved without heavy machinery.
Drive Assembly Options
C-Drive. The chain drive setup provides mechanical advantage by increasing pump speed as compared to wheel speed. The HS-2 and HS-3 models propel the pump at a higher speed than the wheel. The slots on the long shelf accommodate the 500 and the 610 Randolph-Austin peristaltic pump. The chain drive can also be adapted to drive a small 100-PSI peristaltic pump.
D-Drive. With a short shelf, the Wheel-Treater can be adapted to direct drive the 250, 400, 500, and 610 Randolph-Austin peristaltic pump. This is the simplest and most maintenance free setup. The rate of chemical injection is controlled by wheel speed and tubing diameter.
Z-Drive. The long shelf can also accommodate the Z-Drive, which adds an adjustable Zero-Max gearbox for pump speed control independent of the wheel speed. Comparatively, the typical Z-Drive has about 1/10 the chemical output of the D-Drive model. With a reverse sprocket ratio, the Z-Drive output can be doubled. The strong point of the Z-Drive is adjustability.
Increase the control of the Wheel-Treater by adding one of the following optional accessories:
- Zero-Max Gearbox
- PVC 3-way valve
- Cat`s Eye Tachometer
Each additional accessory increases the control of the chemical pump speed, thereby further controlling the chemical metering rate. Any combination of these accessories can be added to the Wheel-Treater.
The Wheel-Treater is predominantly comprised of stainless steel. The peristaltic pump housing is aluminum with a stainless steel option. The safety fenders are ABS plastic. Water can be gravity fed or pump fed into the intake port. Typically only 2-10% of the total flow rate is channeled into the Wheel-Treater. The distributor manifold sends water to the wheel at an 11 o`clock position on the runner. The water then drains from the runner at a 6 o`clock position.
The Randolph-Austin peristaltic pump has stainless steel sealed bearings. The pump mounting stage will accommodate two smaller pump sizes and the option of a Zero-Max gearbox drive. Various tubing adapters are included with every unit, making connections fast and easy. The peristaltic pump will accommodate two tubing sizes.
The Wheel-Treater has large lifting handles on both sides for portability. The runner outflow is completely contained with a 6`` NPT drain outlet.
Electric Chemical Pumps
The Vario-Ject line of chemical pumps is rugged and dependable and can inject high viscosity liquid chemicals up to 100 PSI. There are two types of Vario-Ject pumps: the Vario-Ject GearPump and the Vario-Ject PeriPump. Both are 90-volt DC-converted speed-controlled.
The Vario-Ject GearPump uses a Teel brass gear pump that can pump against a pressure of 100 PSI.
The Vario-Ject PeriPump uses a Randolph-Austin peristaltic pump that can pump against a pressure up to 25 PSI.
The Chemstream Vario-Ject PeriPump system consists of a variable speed DC gear motor coupled to a Randolph-Austin peristaltic pump. This provides finely tuned control over chemical feed with no possibility for siphoning or waste. The only thing that comes in contact with the chemical is the inside of the tubing. AMDTreat 252 is injected in the treatment building followed by the injection of EverFloc 200W at the head of the Aero-Troff. Both products are designed for outside storage throughout the year.
In addition to the Wheel-Treater and Vario-Ject lines of pumps, Chemstream can also supply pumps from the following companies:
- Peristaltic Pumps
- Blue-White Industries Flex Flow Pump
- Stenner Pump
- Electric Pumps
- Pulsafeeder Pump
- LMI Pumps
- Piston Pumps
- A & F Piston Pumps
