Williams V Dual Seal #30950

Product catalog summary

Overview: The document outlines specifications and operational guidelines for Dual Seal Plunger metering pumps, emphasizing high reliability, corrosion resistance, and ease of maintenance. These pumps are pneumatic, offer high flow turndown, and are intrinsically safe, replacing the W&D series.

Pump Features: Key features include a compact stroke adjuster, TFE composite bearings for guided movement, a double sealing arrangement, and simplified lubrication. The pumps use TFE composite seats for check valves and have a threaded port for seal leakage indication.

Materials: Wetted parts and check valves are made from 316 stainless steel, with Elgiloy springs and TFE seats. The pneumatic section includes anodized aluminum components and Buna N piston seals.

Performance Specifications: The pumps operate over a wide range of stroke rates and lengths, requiring a 25-micron filter in the suction line. They are suitable for flooded suction conditions with a recommended suction inlet pressure of 1 to 10 feet. The maximum viscosity is 4500 SSU or 960 CP, with a flow turndown ratio of 100:1 and accuracy of ±0.5%.

Operating Cycle: The pump operates through a power stroke and a suction stroke, driven by air or gas entering and exhausting from the pneumatic drive cylinder.

Accessories: Accessories include air or gas dryer-filters, pressure regulators, micro flow switches, automatic dump valves, and liquid chemical filters, each with specific models and specifications.

Recommendations: Use a pump setting gauge for flow adjustment and install a check valve in the discharge line. Ensure the air/gas supply is regulated and free from particulates.

Pump Selection and Operation Procedures:
1. Pump Selection: Ensure the pump meets flow and pressure requirements using the performance table.
2. Volume Per Stroke Calculation: Calculate volume per stroke using discharge pressure and flow curve.
3. Stroke Rate Calculation: Convert flow rate to cc/min and divide by volume per stroke.
4. Air/Gas Supply Pressure: Add 200 PSI to discharge pressure for positive injection.
5. Performance Curves: Use curves to determine pump capabilities and air pressure.
Control Methods: Use MK XIIA Controller and solenoid valves for automation.
Material Selection: Choose plunger and seal materials based on chemical compatibility and conditions.

Overview of Williams "V" Series Pneumatic Metering Pumps:

Performance: "V" Series pumps offer high accuracy and a flow turndown ratio of up to 100:1, generating pressures up to 10,000 PSI. They meet NACE and FDA standards for corrosion resistance.

Quality: Pumps undergo performance testing and are covered by a warranty for performance and manufacturing defects.

Safety: Pneumatic operation ensures intrinsic safety, and corrosion-resistant materials allow use in harsh environments.

Simplicity: The compact design facilitates easy installation and maintenance.

Materials and Specifications: Available in various models with different plunger and piston diameters, using materials like ceramic and stainless steel for different applications.

Applications: Suitable for industries such as power generation, oil production, water treatment, and chemical processing.

Accessories: Enhance functionality with accessories like dryer-filters, pressure regulators, and automatic processing units.

A) Use The Following Performance Flow Curves* in Order To: Step 3: From step 1 convert your actual flow to cc/min.1gallon 1) Determine the flow capability of the pump you have selected. If you have sized the pump too close to the upper or lower stroke rate limit,you may wish to change to a different pump size.Of course you can also change your flow for a given stroke rate by adjusting the stroke length.Example: x3785 cc x 1 day x1 hr =2.628 cc day gallon 24 hrs 60 min minNow divide 2.6 cc/min by the answer in step 2.2.6cc Example: Application:1 gallon per day @ 3000 psi Step 1: > 1 gallon per...
