Pump package manufacturer Calder uses Solid Edge to meet industry standards and save both time and money

Precision at an early stage

One of the key conditions for Calder is to design for ease of manufacture, assembly and maintenance yet, sometimes, the design team only has a week in which to produce an initial design concept. “What I like most about Solid Edge is that I can quickly make several models with all the major parts and compare the best options for process flow, ease of access for maintenance, footprint and cost,” says Ben Monkton, lead mechanical engineer at Calder.

Synchronous technology supports speedy geometry changes

Calder buys specialist components such as diesel engines, motors and high-pressure pumps and these are often supplied with a full 3D model of the whole assembly. Use of Solid Edge enables designers to incorporate such models quickly and easily into the overall package. If any amendments are required, they can easily be done using synchronous technology, which does not require access to design history.


“Synchronous technology is very good for altering geometry, for example deleting a part, removing a hole or changing the length of a shaft,” says Morgan. “If, for example, I get to the end of a design for a tank, I can use synchronous technology to make very specific changes without affecting related items such as fillets. What works well is the ability to move between synchronous technology and ordered capabilities, using them both. I would, for example, always design fixed items such as hole patterns within the ordered environment.”

Customer service and cost-effectiveness

“Our use of Solid Edge saves a huge amount of time in the workshop,” says Elliott-Moore. “Thorough detailing may add hours in the early stages but the end result is a more complete design because we are addressing potential problems before they arise. If we put two extra hours of design time at the front end of the process and prevent a problem at the assembly stage, then we not only have a better product, we typically save 20 hours of shop floor time.”


Because everything is generated using Solid Edge, it is easier for Calder to prepare bills of materials (BOMs). “We know quantities and costs before we order and can avoid waste,” says Elliott-Moore. “In addition, we can give customers accurate lead times.”


Calder has a turnover of £25m, 75 employees and a state-of-the-art test facility. Sales recently rose by 260 percent over a five year period and according to Ian Calder-Potts, chairman and founder of Calder, the use of Solid Edge certainly contributes to business success:


“I can sit with a customer, use Surface Pro as my tablet to share a 3D model and show that we fully understand the customer’s needs and the specific application,” he says. “Our customers are looking for more than a safe and reliable pump; they demand engineering competence and Solid Edge enables us to demonstrate our capability.”

Our Clients

The tailored update training we attended was very informative and was delivered by a competent and knowledgeable adviser. The instructor was very happy to go off topic during the training to help with any other questions that we had with Solid Edge.

FSM Manufacturing Ltd

NX is an industry-standard product and we are a startup company, but we now know that we could not have managed without it. We knew that NX is robust and utterly predictable, and with our ambitious timescales that is exactly what we needed.


A boat is a very, very complicated product, but we can find no limitation with NX and Teamcenter. There is nothing that we cannot do using NX and It is extremely easy to locate parts with Teamcenter for re-use or resizing.

Sunseeker International Ltd

Teamcenter gave us the greatest possibilities for a product lifecycle system - the ability to track samples, costing, bills of materials for the factory and much more. It is one of the things that will allow us to stay relevant and comptetitive, improving our speed to market.
