The John Crane T4111 is a revolutionary new single-use cartridge seal that simplifies the sealing process for applications using aqueous solutions, making it suitable for industries such as wastewater treatment, food and beverage, and mining. It is recommended for use on centrifugal and rotary pumps, and similar rotary shaft equipment.
The name was derived from the total cost of repair. When considering the expense of shipping, handling, and inventory management in many cases it is more economical to purchase a new seal than repair it.
Users will benefit from cost savings, simplified installation, and reduced maintenance.
The Type 4111 cartridge seal bridges the gap between functionality and cost, making it a sensible option to replace certain component seals or upgrade from packing. It is a practical solution for small, lower-duty pumps that conform to ANSI and DIN standards.
The John Crane 5610 Series is a modular cartridge seal family that includes interchangeable elastomer bellows, metal bellows, and elastomer O-ring pusher seal designs. A common seal head/mating ring set, utilized throughout all versions, is reversible to allow rotating seat/mating ring or rotating seal head operation, and is interchangeable with metal bellow seal heads. The seal has an optional quench gland (5610Q) with carbon ring throttle bushing. Many features and benefits include having a speed up to 5000 fpm/25 m/s, temperatures to -20º F to 400º F, and pressures up to 3.000″/75mm: 300 psi(g)/21 bar(g) max.
COOL FACT
It has a non-clogging wave spring outside the product.
The video shows a leaking mechanical seal. When this happens it can spark many other problems in its wake. The pressurized fluid can often enter the bearing housing causing the lubricating oil to emulsify (looks like mayonnaise) which leads to bearing failure and coupling and/or possibly motor damage. Correct leaking seals as soon as they are discovered because further issues can result. The mechanical seal plays a very important job in the life of a pump and should never be ignored or considered an afterthought.

John Crane improves strength and performance of fiberglass sucker rods
Field trials began late April
Improvements are Company’s response to customers’ needs for better pull strength and reduced downtime
Sugar Land, Texas, May 6, 2015 – John Crane today announced it has begun field trials to test its next generation of fiberglass sucker rod designed to reduce operation downtime and improve pull-strength for oil well operators. The next generation design is a result of customer feedback requiring more strength and reliability of fiberglass sucker rods.
“We’ve utilized our vast engineering expertise to make significant advancements in the development of fiberglass sucker rods,” said Dustin Martin, engineering director, upstream pumping. “It demonstrates John Crane’s commitment to the continued growth of its customers and the oil and gas industry.”
The rod is manufactured at John Crane’s Big Spring, Texas location next to the new research and development lab that has advanced testing capabilities for quality assurance verification, and product development and analysis. The next generation fiberglass sucker rod provides oil producers added flexibility, particularly in more challenging well conditions such as wells with higher load requirements or corrosive conditions. The corrosion-resistant rod provides an average working load that is at least 25 percent higher than all other available fiberglass rod alternatives.
Additionally, it minimizes costly unplanned downtime with its increased ability to remove stuck pumps with a one-time pull load capacity that is at least 30 percent higher than other alternatives. It also facilitates easier and faster removal of rod strings due to a predictive end fitting failure mode at the connecting pin that alleviates fiberglass splintering and broom-sticking.
The next-generation fiberglass sucker rod is a direct replacement of previous generations of product with the same overall length.
“We have simplified the process of transitioning to the next-generation product by using the same materials and API-standard connections, which will allow more customers to realize its value quickly,” said Martin.

CHICAGO (30 Sept, 2014) – John Crane introduces the AURA™ 220 Gas Seal representing the next-generation of advanced gas seal technology and the first to be unveiled under the brand name AURA.
The new technology uses a common global design and patented polymeric sealing device with Active Deflection Control to help customers reduce operating and transaction costs. Additionally, the performance range of the seal has been expanded, improving its performance when operating in high pressure and temperature environments. The AURA™ 220 Gas Seal operates in a pressure range up to 220 bar, or 3240 psi, and a temperature range up to 200 degrees Celsius, or 390 degrees Fahrenheit.
Several additional technology advances help to cut the total cost of ownership for customers:
Reduced leakage lowers customers’ operating costs and protects the environment
Enhanced rotor design extends scheduled maintenance periods and lowers costs
Customers also gain access to localized technical expertise from the largest global service network in the industry – more than 230 sales and service facilities across 50 countries. Technical support and troubleshooting from service and reliability engineers is available through the global service network on the widest range of applications in the industry. In addition, the service network has broad capabilities around power transmission couplings, hydrodynamic bearings, filtration and seal support systems.
Duncan Gillis, John Crane’s President and CEO, said: “With an established track record of reliability and supplying highly-engineered critical components to our customers, we’re proud to continue building on our innovation heritage and introduce a new family of gas seals that represent the next-generation of sealing technology. Our patented technology and large service footprint has put us in a unique position to continue helping our customers achieve their goals and supply energy around the world in a way that is safe and environmentally responsible.”
About John Crane gas seals
In 1968, the first gas seal patent reinforced the company’s reputation as a world leader in sealing technology. Innovation continued when the company introduced a non-contacting, gas-lubricated seal in the 1980s, and in the 1990s, designed a next-generation gas seal for pumps that handle environmentally sensitive liquids. Applying this latest technology to a standard American National Standards Institute (ANSI) or American Petroleum Institute (API) pump will assist customers to meet or exceed the U.S. Environmental Protection Agency’s (EPA) stringent regulations for hazardous emissions. Today, the latest John Crane gas seal technology is used by thousands of customers across the energy services sector, including mid- and downstream oil and gas segments. The new AURA family of gas seals will provide customers access to the latest advanced gas seal technology to support their evolving gas production and processing demands.
