Pump Skid Packages
Hazardous area and safe area. Onshore and offshore. Industrial and process. Standard and bespoke. We design and manufacture pump skid packages for so many different applications. Read on below for a little information on pump skids. Or scroll further down to see just a few examples of pump skid packages we have supplied over the last forty years.
What is a Pump Skid?
The term ‘pump skid’ is commonly used in the energy sector. It generally refers to a pump and its associated equipment mounted onto a sled or skid. Traditionally, these sleds were used to move heavy objects, such as logs, across the ground. In time, the term developed to include a pump system mounted onto a fabricated skid (often now called a base frame) and frequently positioned on site. Not necessarily dragged into position as was the original meaning.
Pump Skid or Pump Skid Package?
People use these terms interchangeably. That said, there is a difference. A pump skid is generally a pump and motor, and other basic components mounted onto a skid. Whereas, a pump skid package usually refers to a more comprehensive system that includes not only the pump and motor, but also other auxiliary equipment required for a complete solution. This could be valves, filters, pressure gauges, and flow meters, as well as electrical and control systems for operating and monitoring the pump. The package may also include accessories such as vibration isolators, insulation, and weatherproofing to protect the equipment from environmental conditions.
A Selection of our Pump Skid Packages
Some of these pictures are from our original factory in Gregory’s Bank in Worcester (Gregory’s Bank is now a housing estate). Some are from our new factory (we moved in 2011) just 2 miles away. As a manufacturer for over forty years, our experience is extensive. These pictures are, therefore, just a tiny sample of our supply history.
The orange, modular waste injection pump skid operates in a remote onshore location. We designed each module to be light enough to be lifted into position by a helicopter. The twin-pump unit is a chemical injection skid package that utilises the HDP 70V variable stroke plunger pump. These pumps allow a variable flow rate (0-100%) via electric, or manually adjustable stroke control, whilst the pump is on or off load, removing the need for a VSD. The offshore waste injection pump skid pictured is a unit we built and despatched in 2023. This electric-powered pump skid will operate in a Class 1, Div. 2 (Zone 2) environment.
Modular Pump Skids
On existing offshore platforms, space and access are often an issue. Thus, where a pump package is an addition to existing equipment, the unit footprint is crucial. Even where the pump package is to replace an existing unit, getting the pump package to the location is generally challenging. Designing a pump skid for these situations is something we relish. However, despite efforts to reduce the size of the pump skid, there are instances where a modular skid remains the only viable option for on-site positioning of the equipment. In fact, we have seen a significant increase in requests for modular pump skids over the last 10 years.

These packing cases contain a modular pump skid that has recently been despatched to our customer. This pump skid is for offshore waste injection duties on a platform with very limited access.
Compliance with International Standards
Our pump skid packages are meticulously engineered to comply with international standards and customer specifications. Most of our pump skids are ATEX, NORSOK, IECEx, or CSA compliant. Every aspect of the design is tailored to align with both regulatory compliance and the precise needs of your operation, delivering a solution that is not only compliant, but also efficient and built to last.
Industrial Pump Skid - Examples
Cleaning Dies used in Animal Feed Processing.
This pump skid will use high pressure water to clean dies used in animal feed processing. At the quotation stage, we ran a series of tests to establish the most efficient pressure and flow for the application. Based on these tests, we configured the unit to pump 21 litres of water per minute at 2,600 bar. This ensures the dies are cleaned correctly with minimal water consumption. Read the news item.
Formwork Cleaning in Construction
Looking for an easier method to clean formwork? This high pressure waterjet pump unit allows you to remove anything from light concrete residues to heavy encrustation from formwork of varying materials. The use of high pressure water is more efficient and produces superior results to traditional methods of cleaning. Check out this news item, Construction company recognizes the advantages of high pressure water.
Cleaning in Food and Beverage
Many cleaning tasks traditionally relied on the use of chemicals or high energy consumption methods. However, more and more customers are turning to resource-efficient, ultra high pressure water. People recognize UHP water as a clean and efficient process for cleaning in food and beverage production. Discover the advantages of high pressure water in the food and beverage sector.
Nuclear Decontamination
Our bespoke design and build experience enables us to create reliable, efficient pumping solutions for very industry-specific applications. We offer solutions for removing contamination from various sources, such as process parts, large waste containers, or the walls of a cooling pond. When it comes to processing waste wash water, minimizing water usage is crucial from both an environmental and economic standpoint. To achieve this, we utilise variable speed drives to regulate the pumps and ensure precise water delivery. Our product range for the nuclear sector includes washdown systems, cooling and flood pumps, abrasive and cold cutting, and tube, pipe and tank cleaning.
Process Skid Package - Examples
Methanol Injection
Our bespoke design experience for methanol injection projects is significant. Methanol injection pump skids often have to comply with both hazardous area requirements and stringent customer specifications. We offer a variety of options including on-skid storage tanks, floor or skid mounted environmental enclosures, local or remote control, monitoring, and data acquisition and logging. More about our methanol injection pump skid packages along with a list of their typical features.
Hydrate Inhibitor
Designed, built, and tested in Worcester, this hydrate inhibitor injection pump skid meets the very specific requirements of the end user. To operate in the warmer climes of the Persian Gulf region in ambient temperatures of up to 50°C, we fitted this pump skid with a protective enclosure and specialist cooling equipment. The unit builds on our vast experience in the supply of bespoke Methanol Injection and Chemical Injection pump packages for hazardous environments, both onshore and offshore.
Chemical Injection
We design and manufacture of API 674 and API 675 chemical injection pump skid packages. Whilst we do mount our pump packages in a crash frame, or in a container, for chemical injection applications, our customers generally require skid-mounted packages. In addition, skids minimise unit cost and maximise maintenance access.
Cooling Skid
These cooling pump systems are generally skid mounted, but we do offer various options to suit the application and operating location. For instance, a popular choice is a skid base with an environmental enclosure covering the equipment. Whilst protecting the equipment from the environment, an enclosure has other benefits. These include the options of noise attenuation, heating, lighting, internal maintenance crane, fire and gas detection systems, and design to account for explosion/blast loads.
Well Service Pump Skid - Examples
Waste Injection
We have been at the forefront of the development of waste injection pump units for offshore drill cuttings injection since the 1990s. Previously, these units were known as cuttings re-injection or CRI. Cuttings re-injection is an environmentally responsible and cost-effective disposal method for offshore waste. In addition to the many pump skid packages we have supplied for offshore use, we designed and manufactured a 40-ft road-going unit for an onshore oilfield.
Well Service
Our well service pump skids are usually capable of a range of well service applications. With maintenance and well integrity critical, our in-house design and engineering team focuses on safety and reliability to ensure our well service pumps meet the high expectations of our customers.
We also offer pumps designed specifically for well stimulation applications. These pump packages often require higher pressures than their well service counterparts. However, they are all designed, built and tested under one roof at our factory in Worcester, UK.
