4 Reasons to choose AODD pumps for chemical processes

Thursday, September 20th, 2018 von admin

Technical paper by Erik Solfelt:

Thanks to its simple yet innovative design, the AODD pump has proven to be able to consistently meet the demands of chemical processors while building a reputation as a go-to pumping technology where basic fluid-transfer capabilities are required. The AODD pump, which possesses a stable of notable operational characteristics, has become a first-choice technology for chemical manufacturers who are searching for a pump that meshes cost-conscious air consumption with reliable and safe production rates.

Compressed air motors for drum pumps

Monday, September 10th, 2018 von admin

Energy efficiency and reducing the operating costs is important as well for user of drum pumps. With the development of the new MDx compressed air motors, Lutz has taken account of this requirement.

With the oil-free, 1000 watts air motor you can achieve the same delivery capacity with 20 % less connection pressure and 4 % less air consumption comparable to other products. The motors have a good start-up behaviour also with low pressure.

Wilden: 13 mm (½”) Clamped Metal Pump

Friday, September 1st, 2017 von admin

This 13 mm (½”) clamped metal AODD pump PS1 is equipped with the energy-efficient Pro-Flo Shift Air Distribution System and its clamped configuration allows for easier maintenance, diaphragm replacement and cleaning.

The footprint of this AODD pump matches that of the Wilden PX1, which enables direct replacement of a PX1 with no repiping necessary. With less components and 7% more efficient than the PX1, the backward capability of the PS1 makes it an easy way to enhance and upgrade existing pump performance.

Tapflo: New series of diaphragm pumps

Wednesday, June 28th, 2017 von admin

The new TC pumps are fitted with LEAP – Low Energy Air Pump – technology used in AODD pumps to reduce the minimum operating air pressure by reducing internal losses and friction. LEAP uses a indirect system to detect the position of the diaphragm shaft controlling the diaphragm movement automatically.

The TC pump is able to start pumping at 0.1 bar without stalling. Key benefits are

Almatec: High-Pressure Pump Series

Monday, July 4th, 2016 von admin

Almatec-AHD_AHS SeriesThis new high-pressure pump series AHD/AHS are developed for applications up to 15 bar (218 psig) such as filter press applications.

The “D” in AHD stands for Duplex, which means the reinforcement of the drive pressure is more than 2:1 by the internal pressure boosting stage. This is achieved thanks to a maximum drive pressure of 7 bar (100 psig), which allows the AHD to build up discharge pressures up to 15 bar (218 psig). AHD Series pumps are available in three sizes (AHD 15, 25 and 40) with maximum capacities of 4, 10 and 20 m3/h (17, 44 and 87 gpm).

The new AHS Series, which does not include an internal pressure booster, features an extremely rugged housing making it suitable for higher discharge pressures. The “S” in AHS stands from Simplex, meaning the drive pressure is transferred to the medium in a ration of 1:1.

Wilden: Stallion AODD pumps now available with Pro-Flo

Friday, September 18th, 2015 von admin

Wilden_PS_Stallion_groupThe Stallion series are developed for pumping fluids with high solid content. A shock-absorbing polyurethane screen base absorbs the impact from constant assault by solid particles. The pumps also feature a large internal clearance and flow-through design to keep the pump from clogging; an integrated suction strainer; and an altered ball/seat check valve assembly. These pumps are made for rugged utilitarian applications that require a robust design.

Stallion pumps now also come equipped with the Wilden Pro-Flo Shift ADS.
