Aod Pumps: Repair it or Replace it?

Ah Aod pumps. They have been around for years for pumping everything from wastewater to oil slurry to sludge. Almost every pump distributor out there has either pushed Wilden, Sand Piper or some other air operated diaphragm pump option at least historically any way. As these pumps age, end users and operators have the issue to grapple with: do I repair my AOD pump or do I replace it? Can I still tolerate my energy bill from Aod pumps or is there a viable alternative? A well known defense contactor pondered these questions and more with a query to Wastecorp’s pump engineering dept.

Air Operated Diaphragm Pump

For facilities looking to upgrade existing air operated single or double diaphragm pump systems, now could not be a better time to check out Wastecorp’s new air driven pneumatic Mud Sucker 3” Series. We are now into Mud Sucker pump month at Wastecorp and we are pleased to launch several new models and savings promotions for this wildly popular Wastecorp brand pump.

What is An AOD – Air Operated Diaphragm Pump?
An air operated diaphragm pump (AOD) is a type of pump that is either mechanically driven with an air motor or driven exclusively using an air. Usually a compressor or air hose line in the facility provide the power for the pump. These pumps are offered in single diaphragm versions or double diaphragm versions which are called air operated double diaphragm pumps (AODD).

What Are Some Examples of Air Operated Diaphragm Pumps?
The Mud Sucker 3FA-AP features a  self-lubricating reciprocating air cylinder, 6” bore x 3” stroke, and adjustable solenoid. The air motor is mounted and supported vertically over the pump body, with a heavy duty 13” dia. Santoprene® diaphragm, 3” stroke length and patented contoured velocity channel to aid in pumping tough slurries. Download the fact sheet to learn more.

What Can a Mud Sucker AOD Pump Be Used to Pump?
The Mud Sucker air driven, pneumatic pump series is ideal for industrial wastewater pretreatment, lime slurries, ceramic slip glazing applications and much more (see a more detailed application list below).

Mud Sucker Air Driven Pumps Typical Applications:

Automotive plating and refinishing, pharmaceuticals and biotechnology, paint and ink coatings, pulp and paper, industrial pretreatment, municipal, industrial wastewater treatment. See all typical applications

New Diaphragm Pump Options for Malaysia

Diaphragm Pumps in Malaysia

Diaphragm Pumps in Malaysia

The Mud Sucker Diaphragm Pump is expanding its presence across Malaysia with a wide variety of our Global pump products available in Kuala Lumpur, Kuala Terengganu, Kota Bharu, Ipoh, Kerteh and Dungun. Our diaphragm pumps have made great headway replacing older technology air operated double diaphragm pumps (AODD pumps) across the country due to increased attention on wasted energy consumption and reducing the carbon footprint. In fact, the Malaysian government have been encouraging business across the petroleum, chemicals and food processing industries to rethink the way they use energy and devise strategies to conserve energy.

This directly impacts the fluid handling industry including pump technology. The Mud Sucker diaphragm pump uses mechanical diaphragm pump technology to transfer wastewater, oil sludge, petroleum waste, chemicals and food processing waste. Wastecorp manufactures the Mud Sucker using energy efficient motors and low emissions engines.

One such case is Wastecorp’s involvement with Petronas’s wastewater treatment operations at their oil and gas refineries. The photos you see here picture the Mud Sucker next to the AODD pumps the treatment plant has traditionally been using. Now, Petronas or Petroliam Nasional Berhad, is vested with the entire oil and gas resources in Malaysia and ranks in the top 100 largest companies in the world. When Petronas came to Wastecorp with their wastewater treatment requirments they were under the impression that AODD pumps were the only diaphragm pump available for their application. Petronas didn’t even know that an alternative Mud Sucker Diaphragm Pump technology existed.

The Mud Sucker pumps are put to work at some of Petronas’s refineries to pump all sorts of wastewater including oil slurry, wastewater and muddy type slurry. For many of these applications the Mud Sucker 3B Series with check ball engineering takes slurry and solids and makes it more productive to transfer by diverting these fluids to the Mud Sucker’s exclusive contoured velocity channel. The chances for clogging are reduced because the check balls help to mash up solids. Check out some of our Malaysian pump installation photos  and contact Wastecorp about the availability of Mud Sucker Diaphragm Pumps in your area.

Pumps: How to Maintain a Continuous Flow and Minimize Pulsation

Pulsation dampening wastewater pumps

Pulsation dampening wastewater pumps

With pumping applications, one of the challenges you face especially when pumping thinner liquids, is to maintain continuous flow without “jerking the hose” or disruptions in pump productivity. One of the consulting engineering firms we have worked with in California illustrates this point well:

“We recently specified your Mud Sucker Diaphragm Pump for one of our client’s projects. The contractor must now provide a continuous flow, as much as possible. While this is a solids handling pumping application, the client frequently has to pump thinner fluids. He has found that there is “jerking in the hose” for lack of a better term when pumping thinner water like consistency. What do you recommend as a solution for this issue.” Thanks – Josh M. Sacremento, CA

Josh, pulsation dampeners are a time tested solution for many continuous flow issues pump operators have. Wastecorp manufactures air chambers for every diaphragm pump model we sell. While we prefer to specify these with the pump at the design stage, there is no problem in sending these for contractor installation for the current set up. All we need are some photos of the existing application configuration and we can go from there.

Positive displacement pumps by nature, generate a pulsating flow. When the ball flapper valve opens and closes, the momentum of the liquid reacts in the form of water hammer, which is absorbed by the hose or pipe. By installing a pulsation dampener, it will act as surge suppressor and reduce turbulence in the pipe. The increased volumetric expansion and absorption of the fluid results in a substation reduction of water hammer, as the below graph illustrates.
