Cast Bronze Simplex Strainers

Cast bronze simplex basket strainers for 3/8" to 12" size pipelines

Keckley Model BGFV bronze simplex strainer

We offer cast bronze simplex strainers for 3/8" to 12" size pipelines amongst five models from three manufacturers.  Use our differential pressure calculator to compare the various models from a performance standpoint.

 

Start by selecting the connection size, then input your maximum flow rate in gallons per minute (GPM), next select the desired retention.  The default values for specific gravity (Sg) and viscosity (SSU) are based upon water and water-like fluids and you can input your specific Sg and select a more viscous fluid range if needed.  The chart will automatically update reflecting the calculated initial clean differential pressure.  Note the maximum flow rate is based upon water; the flow coefficient values (Cv) are there for reference and can be used for calculating the overall differential pressure for your piping system.

 

You will note that 3 of the 5 models have very similar performance, so if your flow rate isn't near their maximum, your choice will likely be based upon features, pricing and lead time.  If your flow rate is pushing the limit, the Eaton Model 72 might be a better choice.

 

You want to size your strainer such that the initial clean differential pressure is ≤ 2 PSIG; the time to clean the basket will be when the initial clean differential pressure increases by about 5 PSIG.

 

Although industrial straining baskets can withstand 15-20 PSIG differential pressure, remember that the rate of clogging increases exponentially (assuming a constant particle load) and this is because as the basket surface area becomes clogged, there's less open area to handle the same flow, so indicating the need to clean the basket at (for example) 7 PSIG provides a little time to react before the critical 15-20 PSIG zone is reached.

 

When comparing strainers you can look at their Cv values and the one with the higher value will have a lower differential pressure.  This equates to a longer time between the necessity for basket cleaning and related to that are labor hours and exposure of employees to the fluid.

 

The main difference in features has to do with the closure style; the model 72 has a quick-opening yoke style cover whereas the others have a bolted closure requiring tools.  The Titan BS95 and Keckley BKF7 cast bronze simplex basket strainers are specifically "lead-free" and suitable for potable water applications.  Use the table below to download the corresponding catalog pages, engineering information and outline drawings for the strainer models you wish to compare.

We can provide you with isolation/vent/drain valves as well as differential pressure gauges (including 4-20mA switch) if required.

 

If you complete our strainer inquiry form we can advise which model is most appropriate, provided discounted pricing and lead time.  You can also call us and we can look-up pricing and lead time on-the-spot! (908.362.9981) or send an email for a prompt reply to all of your questions.

 

Its important to remember that selecting "right strainer" for your application involves more than just the connection size, cost and availability.  The units having a lower Cv value might cost less because they are physically smaller and not capable of the same flow rates - or need more frequent maintenance.  We are here to help, so please contact us today!
