Dosing pumps

MAXROY^®: DOSING WITH SAFETY

The MAXROY^® pump is specially designed for pumping specific products, including viscous products. With its industrial design and absence of any dead volume, it can pump and dose products with a viscosity of 3,500 cP and meets the specific requirements of food type applications. Guaranteeing a dosing accuracy of ±1%, even at low pressure, and a controlled life cycle cost (service lives in excess of 20 years have been recorded), the MAXROY^® is the ideal pump for numerous dosing operations.
 

TYPICAL APPLICATIONS

• Chemical industry: Fertiliser manufacture: dosing of amines or paraffin + amines
• Water treatment in explosive atmospheres: Pumping of flocculants, neutralising agents
• Food industry: Injection of starter in cheese-making

ADVANTAGES

Long service life and safety

• Original diaphragm technology giving a service life of more than 20,000 hours(*), due in particular to its specific shape which only operates by unrolling, thus avoiding any elongation or creep of the PTFE
• Leakproof seal provided by a single PTFE-coated or double PTFE diaphragm
• The toric design of the diaphragm increases the leakproof seal
• Hydraulically protected diaphragm

(*) Depending on the type of product pumped, and the service and installation conditions

Control of the overall cost

• Internal safety valve operating in the oil, protecting the pump against overpressure, in particular if there is a blockage in the suction or discharge tubing or accidental closing of the valves
• Diaphragm can be re-used (single diaphragm)
• Maintenance is easy and does not require any special tools

Modularity

• The absence of contour plates enables all types of fluids to be dosed: slurry, viscous, clear, corrosive, toxic, volatile, abrasive, inflammable
• Compliance with the API 675 standard on request
• Numerous options:
  • Special valves for any type of fluid (H2SO4, viscous or abrasive liquids, polyelectrolytes, etc.)
  • Screw or flange connections (ANSI, DIN or ISO, or food grade)
  • Electronic and pneumatic actuators
  • Stroke counter
  • Frequency inverters
  • Multiplexing

TECHNICAL CHARACTERISTICS

• Flow rate: 16 l/h to 1,110 l/h (stroke at 100% - 50 Hz)
• Maximum pressure: 28 bar
• Maximum temperature of pumped fluids: +90°C
• Available liquid ends: 316L stainless steel, PVC, PVDF, Hastelloy C276, 904L or 304L
• Adjustment while running or stopped, from 0 to 100% of nominal flow rate
• Accurate to within ± 1% - API 675 compliant
• Internal safety valve, set in standard version, optionally adjustable
• Single or double diaphragm
• Diaphragm service life can be in excess of 20,000 hours, depending on the type of product pumped, the service conditions and the installation
• Motor mounted with or without flexible coupling

Possible options

• Materials compliant with offshore use of the pump
• Sandstorm protection
• Motor for frequency variation, NEMA mounting, explosion-proof, for specific ambient temperatures
• Liquid end materials on request
• Screw or flange connections (ANSI, DIN or ISO)
• Special check valves for all types of fluid (including concentrated sulphuric acid)
• Electronic or pneumatic actuators
• Stroke counter
• Possibility of multiplexing for reduced footprint
