WET NEWS WATER AND EFFLUENT TREATMENT NEWS Durability and manoeuvrability are two of the most desirable traits that customers look for when selecting a pump to be used on a working site. These features enable con- stant redeployment in different areas whenever necessary while also facilitating the handling of significant flows and solids han- dling capacities. Sykes Pumps' new GP80 eco pump incorporates these charac- teristics and also features their fabled Univac vacuum system – allowing the unit to prime and re-prime automatically from dry. Powered by a Hatz silenced diesel engine, the GP 80 eco is so-named because of its incredi- bly efficient fuel consumption and low emissions. A built-in 35-litre fuel tank guarantees the pump's ability to run continuously for up to 24 hours, providing fuel-efficient functionality for sustained peri- ods of unattended operation. Billed as the small pump of choice for emergency water and waste treatment projects, the GP 80 eco's impressive output specifi- cations and portable, wheel-based design simplify transportation, reducing the set-up time taken to react to urgent situations. Sykes Pumps provides filtration diversion at Seascale treatment works Cover wrap 2018 3" model joins Sykes' hydraulic submersible range In some wastewater projects, the required suction lift is too great for a standard diesel driven pump – necessitating the use of alternatives. Sykes Pumps are no strangers to such applications, and have introduced products that are effective in this environment. The unveiling of their revolu- tionary 3" H80 hydraulic sub- mersible unit demonstrates this, and is perfect for excavations, hazardous areas and other chal- lenging surroundings. Comprised of a power pack, pump end and a set of 20m hydraulic hoses, the H80 is ideal for many market sectors and capable of operating in remote locations where an electricity supply is unavailable. The latest addition to Sykes' hydraulic submersible fleet retains all dependable characteristics of their 4" and 6" models, providing customers with a smaller version befitting of specialist jobs. Chris Graham, sales director at Sykes Pumps, said: "Our hydraulic pumps have been doing exceptionally well for a number of years now, so it's nat- ural that we move forward by introducing a new product with different specifications." "As a company, we are constantly looking to improve our selection of products whilst exploring ways to enhance the service provided to our customers" Chris Graham Sykes Pumps Economical general purpose pump unveiled Maintaining and upgrading wastewater treatment assets is critical to ensuring sufficient capacity on the system and pre- venting any issues associated with reactive or emergency repair and maintenance. There can be no business interruption to the normal operation of wastewa- ter treatment plants, however, even for planned programmes, a temporary infrastructure is often required to bypass the individual treatment process in question and maintain efficient flow through the works. This was the case at Seascale Water Treatment Works in Cum- bria recently when work was required to replace part of the plant, taking a key filtration stage out of commission for a period of five weeks. To ensure the waste- water was treated to the same high standards and flow levels were maintained through the works, pump hire specialist, Sykes Pumps, was brought in to specify, supply and commission an over-pumping solution befit- ting of the scheme. The solution to providing a temporary replacement for the filtration process was two Dis- solved Filtration Units (DAF), which were provided with a suit- able pump and hose configura- tion by Sykes Pumps to divert the flow. The efficiency of the pumping equipment to manage the varying flow levels and high solids content of the sludge was critical to the success of the project. Explains Richard Box from Sykes Pumps: "The Seascale Water Treatment Works is in a remote location in West Cumbria so for this operationally critical project we needed to ensure that the installa- tion would automatically switch to standby if a fault occurred. We needed to ensure that the installa- tion could respond to variable flow rates as the wastewater entering the plant for treatment came from both the sewer and from storm drains." With a maximum flow rate of 90l/s and a maximum solids capa- bility of 52 mm, GP150 pumps were used to pump sludge from the previous process into the DAF unit then from the DAF unit on to the next process at the plant. Each pump was fitted with ultrasonic sensors and controls to enable the flow rate to adjust automatically to the level of wastewater in the sys- tem. This was a critical element of the specification as the DAF unit had to operate with a constant flow of liquid so the flow rates in and out of each unit needed to be carefully managed. By using ADVERTISEMENT FEATURE ultrasonic sensors and controls, this could be achieved without manual monitoring or adjustment. Meanwhile, the telemetry capabilities installed with each pump provided an added back up, monitoring for faults and auto- matically dialling the number of the duty engineer to alert the responsible member of the team if maintenance was required. The duty and standby sub- mersible pumps located in the overflow were also fitted with ultrasonic monitoring and con- trol, along with vortex impellers to aid management of the heavy sludge. The project was completed in just five weeks, with Sykes Pumps providing all commis- sioning and technical support throughout the programme to keep the scheme on track. Richard summarised: "That task relied on the efficiency of our equipment and the added technology and standby kit that ensured all scenarios were cov- ered to maintain an effective diversion through a temporary process for as long as it was required."
