High Pressure Duty

Product catalog summary

Overview: This document provides technical specifications and performance details for high-pressure pumps manufactured by Warren Rupp, including models EH2-M, SH2-M, N25, and N50. These pumps are designed for applications requiring high discharge pressures and are available in various materials such as aluminum, cast iron, and stainless steel.

Specifications:

EH2-M & SH2-M: These models feature a 2" NPT connection, with a displacement per stroke of 0.3 gallons (1.1 liters) and a maximum flow rate of 62 gallons per minute. They can handle solids up to 0.25 inches and achieve a maximum discharge pressure of 250 PSI (17.2 BAR).
N25: This model has a 1" NPT connection, a displacement per stroke of 0.13 gallons (0.5 liters), and a maximum flow rate of 30 gallons per minute. It can handle solids up to 0.125 inches and achieve a maximum discharge pressure of 238 PSI (16 BAR).
N50: Featuring a 2" NPT connection, this model has a displacement per stroke of 0.5 gallons (1.9 liters) and a maximum flow rate of 90 gallons per minute. It can handle solids up to 0.125 inches and achieve a maximum discharge pressure of 238 PSI (16 BAR).

Performance and Features:

The pumps are air-powered single diaphragm models that deliver discharge pressure twice the inlet pressure.
They are designed for filter press feed and applications requiring higher discharge pressures.
The N25 and N50 models use two air chambers to double the air per stroke, providing enhanced power and higher flow rates with less pulsation.
These models feature a non-stalling, non-icing air valve system with shoe-valve technology to eliminate blow-by.

Applications: These pumps are suitable for industrial applications where high pressure and flow rate are critical, such as in filter press feeds and other high-pressure environments.

www.warrenrupp.com 53 High Pressure Duty - Blagdon Blagdon 1" High-Pressure Pumps provide enhanced power in applications where pressure is paramount and flow rate is an issue. Using two air chambers to double the air per stroke, the N25 achieves discharge pressure up to 238 pounds per square inch with flow rates as high as 30 gallons per minute. The N25’s full flow design incorporates an additional air chamber to deliver higher flow rates with less pulsation, so there’s less wear on pipes and fittings. In addition, the pump can start at zero head pressure with no damage to diaphragms and no need...
