W Series
Precise Chemical Injection
W Series Plunger Pumps
The Williams “W’ Series is a piston plunger pump with a mechanical seal. It is capable of precisely injecting chemical into a wide variety of process applications.
Whether you need to inject a catalyst in a reactor for a refinery or high volume batch dosage treatments offshore such as biocides for water and fuel treatments.
The “W” Series pump can deliver up to 90 gph (336 liters per hour at pressures up to 2500 psig (172 barg).
- Flow rates from 9 to 90 gph (34 to 336 lph)
- Discharge pressures to 3450 psi (238 bar)
- 100:1 turndown ratio
- Variety of seal and plunger materials available
- Dual acting pneumatic relay used to cycle pump
- Pneumatic pumps are often the choice for FPSO (floating, production, storage, and operating vessel due to limited space and electrical power)
NOTE :
(1) The minimum volume recommended for any pump should be calculated on the basis of 1/4 inch minimum stroke length per minute minimum speed with controller, or 1 stroke per minute with solenoid.
(2) The maximum discharge pressure is achieved using 150 PSI (10.3 BAR) air/gas supply pressure.

Solar Chemical Injection Pump (SCIP)
Outperforms in Remote Environments Solar Chemical Injection Pump (SCIP)
The Williams Solar Chemical Injection Pump (SCIP), previously known as the Solaroy®, is a highly efficient DC-powered injection pump operated by 12 or 24 VDC power. This solar pump was specifically designed from the ground up to handle a variety of flows and pressures while requiring the least amount of power, making this pump ideal for remote locations where power sources are limited.
The SCIP is available in Simplex or Duplex configurations depending on the flow requirements, easily determined using the Williams app available as a free download on iOS or Android app stores.
This solar pump can run continuously with flows from 2 to 100 gallons per day and pressures up to 5,000 psig. The liquid ends are 316 stainless steel with dual seals and ceramic plungers for long product life and excellent chemical compatibility.
