MXQ ANSI PUMPS

ANSI refers to the American National Standard Institute. ANSI process pumps are those which comply with the ANSI Standard B73.1. You can avail these pumps from MXQ, LLC at competitive prices.

The whole idea of introducing ANSI process pumps was to make the replacement pumps easily accessible. All the ANSI process pumps that we provide are dimensionally interchangeable with other competitive pumps. They feature a back pull-out design. These features of these pumps make them easy to source for facilities and plants. The need to change the pipe design and schematic is completely eliminated. At MXQ, LLC, we can provide you the MXQ G-Line series ANSI pumps, which can be easily interchanged with the Goulds 3196 pumps. The MXQ D-Line of ANSI pumps that we provide can be interchanged 100% with the Durco Mark III pumps.

Overview


ANSI is the standard set by the American National Standard Institute for the engineers, producers, technicians, and manufacturers to produce quality products. B73.1 is one such standard specially set for the centrifugal pumps. This standard covers around 27 sizes of the pumps. This standard sets a key dimension for each and every size. It allows one to interchange products and parts from different brands and manufacturers.

In this category of ANSI process pumps, there are certain standard dimensions, such as:

  • Pump coupling height
  • Centerline distance between discharge nozzle and suction
  • Bolts held down by the pump location

There are three standard lengths of ANSI pumps that we provide:

  • 17.5″
  • 23.5″
  • 33.875″

PUMP SIZES

This ANSI process pump sizing standard is broken down into three main groups.

  • Group I consists of the process pumps with sizes from 1.5 by 1-6 to 3.0 by 1.5-8.
  • Group II consists of the process pumps with sizes from 3 by 2-8 to 6 by 4-13.
  • Group III consists of the process pumps with sizes from 6 by 4-16 to 10 by 8-17.

Benefits


What makes these pumps so widely used is the benefits that they have. Here are some major advantages of choosing ANSI pumps for your applications:

  • Cost-effective Solution: These pumps are cheaper as compared to the other types of pumps. Besides this, they also have a lower operating cost compared to the other pumps.
  • Easily Available: You can easily avail these pumps and its parts from a wide range of vendors.
  • High Hardness Materials: Most ANSI process pumps are made from high hardness materials, which make them strong, robust, and capable of lasting long.
  • High Tolerance: The ANSI pumps that we provide have a high tolerance for most solids.
  • Lower Electrical Consumption: These pumps are designed to operate at low pressures of 70-90 psi, unlike other pumps that require 90-110 psi. This helps save considerably on electrical consumption.
  • Easy Switch: You don’t require reconfiguring impeller, motor, bedplate, coupling, volute or piping locations while switching these pumps.

 


Comparison with DAF Pumps


The following table compares ANSI pumps with the DAF pumps:

  Specialty DAF pumps ANSI Process Pumps
Standard Parts Only sourced from manufacturer. Often originating from Asia. Available with any pump vendor
Operating Pressure Medium to High: 90 – 110 psi Low to Medium: 70 – 90 psi
Solids Tolerance Low High
Tendency to Cavitate High Low

 


Materials of Construction


These pumps can be manufactured from the following materials:

  1. CD4
