HY Red Dosing Pump Series
The HY Red Dosing Pump series are our small and reliable dosing pumps, rated for continuous operation.
Designed primarily for surface mounting with an optional foot mounting stand, the HY series of dosing pump are often used along with cooling water controllers to deliver biocide and corrosion inhibitor into water treatment applications.
HY Dosing Pump - Control Options
Within the HY range we offer a number of different control options with each pump offering the same range of pressures and flow rates listed below.
The HY-BL dosing pump range are continuous flow rate dosing pumps, where the output flow rate can be manually adjusted. The manual control can be operated across 0 - 100% of the rated output and in the low flow mode, allows for precision control of the pump across 0 - 20% of the output, ideal for biocide dosing applications.
The HY-BL includes an input from a volt free contact which can be connected to an optional float switch to stop the pump when a low chemical level is present.
The HY-BC dosing pump range are proportional control dosing pumps to a pulsed input. With these models, the flow rate or speed of the dosing pump is automatically adjusted as the number of pulses coming into the pump changes. When working with a water meter or a pH controller with a PFM output (such as the P7685), as the number of pulses from the control device increases, so does the flow rate from the pump. The HY-BC has a user selectable ratio of either 4 pulses to 1 stroke, 8 pulses to 1 stoke or 40 pulses to 1 stoke.
The HY-BC also includes a volt free input for use with an optional float switch.
The HY-MA dosing pump range are proportional control dosing pumps to a 4-20mA input. With these models the flow rate or speed of the dosing pump is automatically adjusted to an incoming 4-20mA signal. At 4mA or below, the pump is stopped and at 20mA the pump speeds up to the amount set on the front mounted potentiometer, which is across 0 - 100% of the pumps quoted output range.
The HY-MA also includes a volt free input for use with an optional float switch.
HY Dosing Pump Outputs
Despite being packaged into a physically small body, the HY dosing pumps are big on precision. The HY pumps series models offer the following outputs:-
The output flow rates are tabulated below:-
| Model Number* | Output (Litres / Hour) | Pressure (Bar) | Hose Size | Power (Watts) |
|---|---|---|---|---|
| HY-XX-12-1.5 | 0 - 1.5 | 12.0 | 4 x 6mm | 15 |
| HY-XX-09-03 | 0 - 3.0 | 9.0 | 4 x 6mm | 15 |
| HY-XX-06-06 | 0 - 6.0 | 6.0 | 4 x 6mm | 15 |
*XX Designates the control method - BL for continuous operation with manual adjustment with low level cut off, BC for proportional to pulsed input signal and MA proportional to 4-20mA input signal.
HY Dosing Pump Wetted Parts
Each dosing pump in the HY pump range are manufactured using wetted parts in PTFE, PVDF, ceramic, and are fitted with either Viton or EPDM seals. We strongly recommend using our chemical compatibility checker to ensure that the wetted parts are compatible with your process.
HY Dosing Pump - What's included?
Each Dosing Pump in the HY range is supplied ready for operational duty. Each pump is supplied complete with:-
- Injection Valve
- Foot-valve & Strainer Assembly
- Discharge Tubing
- Suction Tubing
- Surface Mounting Bracket / Foot Mounting Bracket
HY Dosing Pump Series
HY-BL
The HY-BL dosing pump series are manually adjustable constant flow rate dosing pumps with a maximum output up to 6.0 Litres per hour and maximum pressure of 12.0 Bar.
Using the front mounted potentiometer the HY-BL can be adjusted from 0 - 100% of the rated output. Using the special low dosing mode, the range can be restricted to 0 -20% of the rated output to ensure precision dosing even at low flow rates.
The HY-BL also has a volt free contact input which can be connected to a low level float switch to stop the pump when there is a low chemical level present.
The HY-BL is powered from a switch mode power supply, to operate from 100 - 240 VAC 50 / 60Hz.
HY-BC
The HY-BC dosing pump series can operate at either a constant flow rate which is manually adjustable, or dose proportional to a pulsed input signal. Both options are available with a maximum outputs of up to 6.0 Litres per hour or 12.0 Bar pressure and selected using the selector switch.
In manual dosing mode the output speed is adjusted using the front mounted potentiometer.
In the proportional dosing mode the dosing pump automatically varies the speed or number of strokes the pump makes per minute based on the volt free signal from a water meter, pH controller or other piece of control equipment. The HY-BC can be adjusted from a 4:1 ratio to 8:1 ratio and 40:1 ratio using the front mounted potentiometer.
The HY-BC also has a volt free contact input which can connected to a low level float switch to stop the pump when there is a low chemical level present.
The HY-BC is powered from a switch mode power supply to operate from 100 - 240 VAC 50 / 60Hz.
HY-MA
The HY-MA dosing pump series can operate at either a constant flow rate which is manually adjustable, or dose proportional to a 4-20mA input signal. Both options are available with a maximum outputs of up to 6.0 Litres per hour or 12.0 Bar pressure and selected using the selector switch.
In manual dosing mode the output speed is adjusted using the front mounted potentiometer.
In the proportional dosing mode the dosing pump automatically varies the speed or number of strokes the pump makes per minute based on the incoming 4-20mA input signal. At 4mA the dosing pump is stopped and at 20mA the output is based on the setting of the potentiometer. The maximum output at 20mA can be varied from 0% to 100% of the dosing pumps rated output.
The HY-MA also has a volt free contact input which can connected to a low level float switch to stop the pump when there is a low chemical level present.
The HY-MA is powered from a switch mode power supply to operate from 100 - 240 VAC 50 / 60Hz.
