Introducing the LPD-Mag
The LPD-Mag is the lowest pressure drop Y-Strainer on the market, upgraded with a magnet to catch iron oxides. The LPD was developed by Metraflex through a complete re-engineering of the traditional Y-Strainer to provide a strainer with a much better pressure drop and at the same time a much higher debris capacity than any…

Read MorePump Basics 2: Pump Curves
When a centrifugal pump is designed, the manufacturer will test the operation of the pump to the theoretical design. Pumps are tested for flow, head (pressure differential), power consumption, efficiency and minimum allowable suction pressures, also known as Net Positive Suction Head Required (NPSHR). Generally, as the pump handles greater flows, the pressure differential it…
Read MorePump Basics – Impellers and Volutes
Centrifugal pumps come in many configurations – in-line, base mounted, foot mounted, single and double suction, vertical and horizontal split case, close coupled and long coupled – the list goes on. No one style is best for all applications. So when should you use which? Over the course of the next few blogs, we are…
Read MoreDo your engineers know that Metraflex has Revit files
REVIT® REVIT® Do your engineers know that Metraflex has Revit files — and all other major CAD drawing file types — readily available to them for Building Information Modeling (BIM)? Only Metraflex, not our competitors, has these BIM drawings. Getting a Metraflex Revit file on the contract drawings locks us in and tells the contractor what to…
Read MoreNeed help designing an engineered piping system?
We offer delegated design services for firms needing this special expertise. Increasingly, project specifications are calling for a “delegated design submittal”, including stamped calculations, and making the contractor responsible for the design of piping expansion. If your project does not require stamped calculations, we will provide you with recommendations at no cost. Metraflex uses CAEPipe…
Read MoreGetting the Most, part 4: Cooling Tower Optimization
In the last part of this series, we talked about getting the most out of your Plate & Frame Heat Exchanger. One of the critical decisions to make about sizing a HX is the approach temperature. The approach temperature is the difference between the inlet temperature of one fluid and the outlet temperature of the…

The following is an excerpt from the LinkedIn page Cooling Tower Industry Topics, a very handy page to discuss the cooling tower industry or ask questions to professionals in this area, including our CT rep SPX Cooling Technologies. To request access to the group please visit this link. Engineers must choose from a variety of…
Read MoreGetting the Most, part 3 – Plate Heat Exchangers
Last time, we talked about pressure drop limitations and how they affect the sizing of a plate heat exchanger. Today we will discuss a couple of other key considerations. First: approach temperatures. Approach is the difference between the outlet temp of one fluid to the inlet temp of the other. Generally speaking for a given…
