AGGRESSIVE CHEMICAL DOSING PUMP


The Roto Aggressive Chemical (AC) Dosing Pump is our product designed for use with aggressive chemicals. Suitability is achieved by using materials of construction that are resistant to the array of aggressive chemicals found across Industry. Progressive Cavity Pumps of the dosing type have distinct advantages over other pump types commonly used for dosing. The main advantages are a steady flow without pulsation, a high degree of accuracy, the ability to handle entrained solids, suction lift and handling of pressure of up to 24 bar.

Dosing Pump

Flow: 0.17 to 132 GPH / 0.68-500 LPH
Pressure: Up to 350 PSI / 24 bar

DISTINCTIVE FEATURES & BENEFITS

  • Capacity is directly proportional to speed.
  • High dosing accuracy of +/-1%.
  •  Low NPSH required & Inherently Self Priming.
  • Smooth & Non-Pulsating Flow.
  • No need to use Pulsation Dampeners or additional valves.
  • No vapour lock & non-clogging
  • Easily handles clean and clear liquids to abrasive, corrosive, shear sensitive, viscous and solid laden.
  • Easily interchangeability with other models by changing few components.

ROTO ADVANTAGES

1. ROTOR
RJ series rotors are available in stainless steel, AC series rotors are available in Titanium or Hastelloy
material options

2. STATOR
The elatstomeric stator is moulded with integral sealing gasket on both ends effectively prevents corrosion of the stator tube. This design ensures that the pumped media remains isolated, not coming into contact with the stainless steel metal tube or bonding adhesive. The stator elastomers include; Natural, Nitrile, EPDM, Chloro-sulphonated rubber, HNBR, Floroelastomer, and Terfloroelastomer.

3. CONNECTIONS
RJ series is available in Stainless Steel 1″ NPT/DIN Connection at Suction and 1/2” NPT/DIN Connection at Discharge. AC Dosing pump range is availalbe in 1″ NPT
Connection at Suction and 1/2” NPT Connection at Discharge in CPVC or Glass Filled PTFE materials.

4. PUMP HOUSING
Designed for 900 interval rotation for ease in installation. Options available in Stainless Steel / CPVC / Glass Filled PTFE materials.

5. SHAFT SEALING
Standard RJ Dosing pumps are available with Single / Double Mechanical Seal and Gland Packing options. These pumps have seal housing in Stainless Steel. AC Dosing pumps have provision for Plan 62 as standard. These pumps have Seal Housing in Hastelloy as standard .

6. TIE RODS
Four SS316 Tie Rods provides torsional stability & greater resistance to corrosion.

7. PUMP LANTERN
Can accommodate various drives including IEC, NEMA C / Gear Motors. These can be directly flanged to the pump without additional couplings or guards.

8. DRIVE OPTIONS
1. 90V DC Motor – 600 RPM Direct Online.
2. 0.37 kW/0.5 HP Geared Motor.
3. Gearbox and Motor as per NEMA/IEC standard.
4. 0.37 kW/0.5 HP Geared Motor with Integrated VFD to optimize and control the dosing process.
5. Servo Motor.
6. Tophat version in bareshaft option.

9. PLUG IN SHAFT
The pump and drive are designed for effortless disassembly, allowing for rapid replacement of rotating
parts and the shaft seal. Dovel pin ensures a secure shaft-to-drive connection, while the retaining ring
safeguards the bearing against contamination or shaft leakages.
