Aquaculture pump unit

New Markets for High Pressure Pumps - Aquaculture

July 2016

A Calder-manufactured high pressure water jetting unit specifically designed for the aquaculture industry is despatched to the Scottish Highlands. This innovative pump unit will operate in conjunction with a range of cage and net cleaning equipment to provide a reliable and efficient solution to marine fouling.

The rugged and remote coastline of the Highlands and Islands provides excellent natural environments for the growing aquaculture sector. However, this remoteness brings with it added time and cost implications for machinery maintenance which is one of the reasons Calder was selected to design and build this pump unit. Although innovative in design to meet the specific industry and application requirements, this unit is based on the tried, tested, and trusted MultiJet range which has been developed over three decades. At the heart of the MultiJet is a Hammelmann vertical reciprocating plunger pump which offers unrivalled reliability and operational time between scheduled maintenance.

Through sound principles of design, careful component selection, and the latest electronic control and monitoring capabilities, this pump unit should give many years of reliable service in some of the most inhospitable offshore environments in the United Kingdom.

Heli-portable well service units

July 2013
To meet the needs of an ever changing market place Calder were recently tasked to find a solution of how to design and transport a 14 tonne diesel driven well service pump system into an area only accessible by helicopters with a 3.5 tonne lift limit. Using creative techniques of design and manufacture, two pump units were built and delivered in a configuration that allows separate air lifts but can be easily & quickly assembled on the remote jobsite ensuring swift deployment.
These projects add to Calder’s already vast reference list of design and build pump packages in either diesel or electric driven format for hazardous or safe area environments worldwide.

Sabre Jetting

Sabre Jetting of Birmingham

June 2013
Yet another Hammelmann pump supplied to a well-established national hydro demolition, surface preparation and tank cleaning company enabling Sabre Jetting to offer some of the most reliable and efficient service within the contracting service industry.
The pumps are mounted into truck tankers providing not only the High Pressure Pump but also water storage of 12m³ and are ideal for projects where there is no access to a suitable supply of water.
The Sabre Jetting fleet of high pressure pumps operate at 1100 or 1400 bar with a flow of 45 or 55 lpm. Each unit has an auto throttle to reduce water consumption which means the pumps can operate for approximately 4 hours without fill up. Another feature is the Euro 4 compliance for access to inner city London.

Calder Gains Certification to BS OHSAS18001:2007

14th April 2011

Calder is pleased to announce that it has gained certification to BS OHSAS18001:2007, the internationally recognised standard for Health & Safety management systems.
Certification was achieved at the first attempt, largely because emphasis has been placed on H&S ever since the company was founded by Chairman Ian Calder-Potts in 1984. Accredited by National Quality Assurance (NQA), the OHSAS18001 system is designed to promote a safe and healthy working environment by providing a framework that allows accredited companies to consistently identify and control Health & Safety-related risks. The standard also helps companies to reduce the potential for accidents at work, helps with legislative compliance, and assists with the improvement of overall performance.

For Calder, the BS EN OHSAS18001 accreditation adds to existing accreditations for both the ISO 9001:2008 and ISO 14001:2004 standards.

Health & Safety has been an important part of the long established Calder Integrated Management System. With zero reportable accidents and zero lost working-time cases for more than 5 years, Calder’s H & S performance is well above the industry norm. Like many responsible organisations Calder Ltd implement an occupational Health & Safety management system as part of their risk management strategy to address changing legislation and to protect their most valued asset – the workforce.

The Calder focus on Health & Safety is equally applied in the interests of customers by designing Calder machines for safe transport, installation, commissioning and operation, by providing Water Jetting Association approved safety training for water jetting supervisors and operators, and by the provision of water jetting Personal Protective Equipment (PPE) manufactured to the best available technology.
