Pumps/Vacuum technology

Pumps/Vacuum technology Companies – Innovations – Products Reliable membrane filter press feed with compact diaphragm pumps at [k]nord GmbH [k]nord GmbH headquartered in Ganderkesee (Niedersachsen/Land of Lower Saxony) totals more than 35 years experience as a specialist in the development and implementation of innovative waste disposal technologies. Innovative services and products of this company allow a sustainable environment protection to be ensured. The range of activities of [k]nord GmbH includes waste disposal and environmental engineering, noise protection and logistics. The filling time and the pressing time take approx. 1 hour each. Consequently, after 2 hours, the filter cake has reached a solid content of up to 80 % and can be dumped into the container standing below the filter press. The weight of the filter cake amounts to approx. 2.7 t per batch. [k]nord GmbH is highly satisfied with the operation of the plant – it runs 24/7, entirely automatically and it is monitored with several cameras. Operating parameters can be both controlled and monitored directly on-site and via an app installed on a mobile phone. Next to the composting plant, there is a new, recently built, disposal plant for mineral and, in part, for organic drilling slurry as well: The drilling slurry with a solid content of 15-20% is brought to the plant in tank trucks from which it is pumped through a screening system (ensuring the separation of sand and stones) into 8 storage basins equipped with agitators. Each batch is analysed in the laboratory in order to determine the most suitable conditioning method for achieving the optimal filter cake. Fig. 3: Membrane filter press at [k]nord GmbH The use of ABEL CM pumps has quickly shown that the overall energy consumption of the plant was very low. According to [k]nord GmbH, 20,000 tons slurry have been treated in 2020 with a power consumption of 22,000 kWh, this translates into a unit electricity consumption of 1.1 kWh/ton only! Fig. 1: Storage basins with agitators Dewatering with ABEL pumps and membrane filter presses In a 24/7 operation, 2 membrane filter presses are fed with 4 ABEL type CM-G-C262 compact diaphragm pumps (each pump delivers a flow rate of 10 m³/h). Before using ABEL CM pumps for this application, [k]nord GmbH tested a different type of pump which operated with a compressed air drive. However, the energy consumption of this pump turned out to be excessively high. CM pumps are in charge of filling the filter presses with abrasive slurries quickly and reliably/constantly. When the pressure of approx. 8-9 bar is reached, the membrane filter presses take over from the pumps and continue the dewatering of the slurries until the pressure of approx. 13 bar is reached. Fig. 4: Fully automated plant monitoring The ABEL piston diaphragm pump is a crucial component for filter press feed. The advantages of ABEL pumps over other pump types are represented by: – a high wear resistance – a high robustness – very long maintenance intervals – a low energy consumption, which allows operating expenses of clients to be reduced Fig. 2: ABEL CM pumps ABEL GmbH Abel-Twiete 1 21514 Büchen, Germany Phone +49 (0)4155 818-0 abel-mail@idexcorp.com www.abelpumps.com 54 PROCESS TECHNOLOGY & COMPONENTS 2022

Pumps/Vacuum technology Companies – Innovations – Products New Plunger Pump Portfolio – pump programme more tightened, standardised and easier Technical changes in the pump programme implicate more power input, standardisation and simplification Panta rhei – Everything flows! Same at KAMAT! As the pump manufacturer from Witten puts it they actively used the Corona-time to work at full speed on the development of their pump programme, in order to achieve further standardisations and hydraulic revisions at their plunger pumps. Now, KAMAT proudly present their new performance list. The pump range with all its technical data is summarised in an overview on a two-sided data sheet. In addition, an overview of the new pump programme is also available in an 8-sided Plunger Pump Portfolio leaflet with a new design. „Reason for our new leaflet are a number of eager efforts in the developments of our systems, aiming and achieving a higher grade of standardisation, maximum input power and further, more simplification“, says chief engineer and Managing Director Dipl.-Ing. Jan Sprakel. Now, the last final details of the planned modifications and their realisation are successfully completed. “We have decided to summarise all technical changes preliminary in this overview leaflet file, which we have already published last year. To be up-to-date, herewith, we have uploaded the leaflet’s online-version for all who are interested. We hope that the portfolio‘s new look, design and format will suit every body and what is more important to us, that it will be helpful to everybody who is looking for the most suitable pump. Much more we are pleased about the occasion for designing and publishing the new brochure and this is the rapid development of our pump programme, with the goal, to minimise the danger of cavitation even further“, says Sprakel. More outline: From now on out of previous 13 pumps only 11 remain in the performance list What has changed in detail: The pump programme has been tightened, unified and has become easier. Out of the previous 13 pump types in the performance list only 11 remained, with no losses but optimisation. The current M-Head has been omitted without the loss of versatility in the available options. The MCH-Head was re-named as M, because it replaces the old M-Head. The MC-Head becomes M2-Head. The new M-Head and M2-Head will be available in any performance level with plate valves and soft valves. With the changeover all heads were reengineered with the objective to achieve lower NPSH-values and thus avoiding cavitation. Furthermore the gear boxes have been revised, with higher performance inputs resulting in generally increased performance level. New conversion kits not needed, pump-heads smaller and lighter in weight from now on From now on the heads are smaller in their design size and thus lighter in weight. The good news: New conversion kits are not needed and all previous mounting parts still fit. According to the manufacturer the gear geometry and intersection stayed the same too. A1- and A2-Head remain the same, just with standardisation of the suction hoses. The benefit to the customer is next to flexibility very clearly the NPSH optimisation with lower values. Furthermore, in each design size there is the opportunity to customise the valve design size depending on the fluid distributed. The integrated oil coolers remain available for the mining industry. The changes at a glance: Pump Performance K40000-3G/400 kW -> Upgrade to K45000-3G/ up to 450 kW K50000-5G/530 kW -> Upgrade to K55000-5G/ up to 550 kW K80000-5G/800 kW -> Upgrade to K100000-5G/ up to 1000 kW = 1 MW K120000-5G/1200 kW -> Upgrade to K150000-5G/ up to 1500 kW = 1.5 MW Pump Heads (A- and M-Head) M-Head omitted MCH-Head becomes M-Head MC-Head becomes M2-Head Both heads can get either plate valves or soft sealing valves.
