Essential Tools for Pump Repair
Like any job, you need the proper tools to do it well – and the same is true for repairing or servicing positive displacement pumps. If you feel comfortable and capable repairing your positive displacement pump, then the tools below will be helpful to get your service completed and your pump back up and running.
But if you don't feel comfortable, that's okay. IEQ stands ready to help you repair simple or complex pump repairs. - October 24, 2024
Reducing Methane Emissions in Upstream Oil & Gas Processes
How electric actuator technology can make a difference
Methane is a greenhouse gas that traps heat in the atmosphere and is the second most prevalent human-made greenhouse gas behind carbon dioxide (CO2). Because methane is more than 28 times as potent as CO2 at trapping heat in the atmosphere over a 100-year period, it has become more critical for governments and businesses worldwide to minimize total methane emissions from industrial processes.
The oil and gas sector emits around 80 metric tons (Mt) of methane yearly, accounting for roughly 40% of total human-caused methane emissions. These emissions may be reduced by over 75% by implementing leak detection and repair programs and upgrading leaky equipment. Methane abatement in oil and gas is highly cost-effective to do. Approximately 40% of methane emissions may be eliminated at no net cost. The automation

Positive Displacement Pump or Centrifugal - Which Should You Use?
What's the best way to determine if you should use a positive displacement pump or cetfrifugal pump for your application?
Positive displacement pumps and centrifugal pumps have different hydraulic designs, resulting in varying application considerations that affect how ideal each pump would be for performance.
Centrifugal pumps utilize a rotating impeller to impart kinetic energy to the applicable fluid
The fluid then exits the impeller radially. The performance of a centrifugal pump is such that the flow rate is variable as a function of system differential pressure or total head. This means it can achieve variable flow while operating at a constant rotational speed:
Additionally, when pumping, the liquid is sheared by centrifugal pumps. What this means: centrifugal performance is significantly affected by the viscosity

Glossary of Plunger Pump Parts
At IEQ, oftentimes we are asked by new or inexperienced engineers and end-users about specific parts for plunger pumps.
In order to help our customers, we wanted to provide this glossary of commonly-used terms for plunger pumps.
POWER END SPECIFICATIONS:
Power Frame - One-piece, close grain, cast iron casting with heavy wall sections, well ribbed to insure rigid construction and designed to fully enclose all working parts.
Gears - Herringbone construction. Typically, main gear is heat treated high grade ductile iron. Pinion gear is cut from forged alloy steel and hardened.
Crankshaft - Heavy center section for mounting main gear. Large diameter crank pins for optimum load capacity.
Pinion Shaft - Machined and precision ground from heat treated alloy carbon steel.
Bearings - Heavy duty tapered roller bearings do crankshaft.

Reciprocating Piston Pumps & Their Applications
In this blog, let's compare the operating cycles of two-check piston pumps and priming piston pumps. Pumps are broadly classified into positive displacement pumps and centrifugal pumps. Positive displacement pumps have many different designs. There are three classifications for positive displacement pumps: rotary, reciprocation and linear. This article focuses on reciprocating pumps that operate using pistons/plungers.
Reciprocating piston pumps are one of the most common pumps and are used in many applications, such as pumping peanut butter in the food industry, pumping grease to lubricate machines, metering and transferring adhesive and dispensing oil in vehicle services. These reciprocating piston pumps are also called stick pumps, as the pumping section resembles a long stick that is intended for use with industry-standard containers.

Pump Cavitation: The Symptoms, Cause, Diagnosis, and Cure
“Hey, come listen to this pump.”
If it's a quiet pump, no one ever asks for a second opinion. This is symptom #1 of a cavitating pump. The pump is loud. Descriptors like “growly”, “rumbling”, or “gravelly” are used to describe the atypically loud sound coming from the pump.
The question you need to answer is: “Does it always sound like this?”
If it was much quiter and all of a sudden made noise, alarm bells should be raised.
Symptom #2. The noise is intermittent. It’s loudest when the liquid is more viscous, the supply tank is near empty, when the pump is runs faster, or the strainer hasn’t been cleaned, etc. The noise is loudest when the inlet conditions are worst.
So ask yourself, “How’s flow?”
If it's slow and takes longer to empty the tanks, that should be concerning.
Enter symptom #3. The flow rate

Criteria for Compression Packing Seal Selection in Pumps
Using the right seal is critical in maintaining safe and efficient operations.
In the vast array of industrial processes, pumps serve as a vital asset, propelling fluids through pipelines, systems and machinery. The efficiency and reliability of these pumps are often contingent upon selecting the right seals.
Sealing products not only prevent leaks but also contribute significantly to the longevity and performance of pumps. However, with myriad sealing options available, choosing the appropriate one can be a daunting task. Understanding the sealing selection criteria is essential for ensuring optimal pump performance across various industrial sectors.
Ensuring Reliability with Compression Packing
Failure in industrial pumps typically occurs due to issues in one of three major areas: the sealing system, the bearing system or hydraulic components. In particular, sealing and packing systems

This article is meant to provide an overview of basic maintenance in high pressure plunger pump applications for industrial use. This article will only touch the tip of the maintenance structure and should be used only as a baseline for maintenance.
Basic Maintenance for High Pressure Plunger Pumps
Proper training before attempting a repair is imperative. Most pump OEM manufacturers offer technical training programs to authorized distributors or dealers. These programs range from one to five days in length. These are sometimes free of charge. It is strongly recommended that you take advantage of programs like these if attempting to repair or refurbish pumps.
The two most common failures seen are:
- Lack of normal maintenance: No oil changes, running with water in the oil, valve seat o-ring damaged (resulting in loss of pressure and pulsation's), running with leaking or worn packings and or broken plungers.
