Pumps - Pulsatron/Pulsafeeder

Industrial pumps move liquids from one place to another, whether you’re handling water, chemicals, or thick, heavy fluids. Most pumps fall into one of two main categories: positive-displacement pumps and cen...

Solenoid Driven Metering Pumps
Solenoid Driven Metering Pumps

Solenoid driven metering pumps use an electromagnet to drive a diaphragm for precise, low-flow chemical dosing. They're compact, affordable and easy to control, which makes them the go-to choice for water treatment and cleaning chemicals.

Features

  • Adjustable stroke rate and length – wide turndown
  • External control – pulse, 4-20 mA and timer inputs
  • Chemical-resistant heads – PVDF, PVC, PTFE and stainless
  • Degassing heads – handle off-gassing chemicals

Choosing a Pump

Provide flow range, pressure, chemical and control method. Include foot valves, injection valves and calibration columns for accurate feed.

Centro supplies solenoid metering pumps for chemical dosing.

Peristaltic/Hose Pumps
Peristaltic/Hose Pumps

Peristaltic (hose) pumps move fluid by squeezing a flexible hose or tube with rollers or shoes. The fluid only touches the inside of the hose, so these pumps handle abrasive slurries, corrosive chemicals and shear-sensitive products without seals or valves to wear out.

Advantages

  • Seal-less design – no leaks and no seals to replace
  • Handles abrasives and solids – slurries, lime, sludge and mining fluids
  • Gentle pumping – protects shear-sensitive products
  • Self-priming and dry-run capable – tolerant of upsets
  • Accurate metering – flow proportional to speed

Selection Tips

Pump size depends on flow, pressure and duty. Running slower extends hose life. Choose hose material (natural rubber, Buna, EPDM, Hypalon) for chemical compatibility. Keep spare hoses on hand, since the hose is the main wear item.

Centro supplies peristaltic hose pumps and replacement hoses for chemical feed and slurry transfer.

Motor Driven Metering Pumps
Motor Driven Metering Pumps

Motor-driven metering pumps deliver accurate, consistent dosing at higher flows and pressures than solenoid pumps. They're built for continuous duty in chemical processing, water treatment and oil and gas.

Pump Types

  • Mechanical diaphragm pumps – simple, economical dosing
  • Hydraulic diaphragm pumps – high pressure and accuracy
  • Piston and plunger pumps – very high pressures
  • Multiplex pumps – multiple chemicals from one drive

Choosing a Pump

Provide flow, pressure, chemical and control needs. Select materials and stroke control (manual, electronic or VFD).

Centro supplies motor-driven metering pumps and accessories.

Like the Pulsatron Series C the Series C Plus offers manual control over stroke length and stroke rate as standard with the option to select an external pace for automatic control. The primary difference is the pressure rating. The Series C Plus offers four distinct models with pressure capabilities to 80 psi, and flow capacities to 30 gpd (4.7 lph), with a turndown ratio of 100:1. Metering performance is reproducible to within +/- 3% of maximum capacity. Our guided check valves, with their state-of-the-art seat and ball designs, provide precise seating, excellent priming and suction life characteristics. Our timing circuit is highly reliable and, by design, virtually unaffected by temperature, EMI and other electrical disturbances.
