Primary Sludge Pumps at a WWTP

Primary Sludge Pumps

Primary Sludge Pump Options

Primary sludge pumps are typically used in municipal Wastewater treatment facilities to transfer digested sewage and sludge. This is a broad pump category that encompasses positive displacement pumps to pump sludge in ranges usually up to about 500 GPM. The choices of pumps vary from double diaphragm pumps, plunger pumps, double disc pumps, rotary lobe pumps, progressive cavity pumps and more.

In todays pump marketplace, there are generally two schools that operators and consulting engineers follow when specifying primary sludge pumps. The first option is Continue reading

Grout Pumps for Commercial and Residential Applications

Commercial Grout Pump

Grout Pump

As the weather improves for commercial grouting jobs it gives us an opportunity to address contractor concerns. One of the comments we heard from contractors who work with grouting jobs before the Sludge Sucker grout pump was made available, is that there was a lack of dependable, compact grout pumps that could easily be moved to job sites with tight spaces. Wastecorp went to work and designed/engineered the Sludge Sucker Professional Grout Pump. Now, this has not been featured on Shark Tank (yet) but we have been thinking about it due to its positive response from construction professionals.  Since then, the Sludge Sucker has become a staple for commercial contractors and public works crews to grout door frames, pilings, slab jacking, void filling, mud jacking and many other commercial grouting applications.

How to Find New Diaphragms for an Old Diaphragm Pump

Diaphragms for any kind of diaphragm pump

Diaphragms for any kind of diaphragm pump

One of the frequent calls we hear from customers is that they either have an older diaphragm pump make or need replacement diaphragms for their newer diaphragm pump. Some genuine replacement parts are easier to find than others. The good news is that replacement diaphragms and other parts for almost any kind of diaphragm pump are available for pumps dating back as far as the 1940’s.

The general procedure for measuring your current diaphragm and getting your pump back to operating condition is easier than you think. There are three general steps to follow to getting the pump parts you need.

Step 1: Measuring Your Diaphragm

Do three quick measurements. Measure the outside diameter (OD) of the diaphragm. Replacement diaphragms generally range from 5” and go all the way up to 15” OD’s. Measure the height of the diaphragm. A tip here is to measure from the bottom of the diaphragm laying on a flat surface to the top. Finally, measure the inner diameter (ID) or the top of the diaphragm. This is especially important so your diaphragm parts supplier can establish where the diaphragm clamps onto the clamping plate.

Step 2: Selecting Your Diaphragm Material

Viton, Santoprene and Neoprene are generally the different varieties of diaphragm materials available. For general wastewater pumping, Santoprene and Neoprene have proven to be effective. For corrosive and abrasive fluids your pump parts repair person may suggest a different material like Viton. You should talk to a pump expert before making this decision however.

Step 3: Have your Pump Make, Model and Serial Number Ready

Your diaphragm pump parts provider can get information to you with greater speed if you have all of this information ready when you order. There are many pump makes out there like Mud Sucker, Mud Hog, Edson, AMT, Homelite, CH&E, Tsurumi, Wilden, Multiquip, Wacker are all makes that have been around for some time and each has their own diaphragm sizing and recommended materials.

Wastecorp is one pump manufacturer who also has a replacement parts division for many makes of diaphragm pumps. They also dedicate a website page to finding the correct diaphragm size. Check it out here

Pumping Out Tanks With Diaphragm Pumps

Mobile Diaphragm Pump

You name the tank that needs to be pumped out and we have heard of at least a few customer applications that correspond with that tank. Underground septic tanks, lagoon transfer, transport truck tankers, locomotive tankers, waste pits and waste vegetable oil drums are among the most popular. What you have to keep in mind is that in most of these applications, you will need a pump that can easily maneuver in areas to access the discharge valve or at least some place where you can place the suction hose.

Randy K. from Columbus, GA, contacted Wastecorp about his settling tank pump out operation:

“I Need assistance to find the correct pumps to transfer mud consistency wastewater, brackish water and abrasive media out of settling tanks at a mining application we have. We have a need for three or four pumps that need to be mobile. We have been told that a diaphragm pump with check balls might work. The pump also needs to be able to handle gritty waste water and slurry. We are pumping up around 8-10’ and pumping out vertically to a screen another 60’ What do you recommend?” Randy K. Columbus GA.

Well Randy, it has long been known in the pump business that when you have a variety of media to pump, your pump must be versatile. The Mud Sucker B Series Professional diaphragm pump is one of those products. Take the Mud Sucker® 3B Series you see in the photo above. This is being transported around a six mile long public space along New York City’s West side. This Mud Sucker pumps everything from septic waste, cleaning up construction wastewater containing aggregate, waste vegetable oil from City operated restaurants and more. The check balls help to manage the solids and if something should get stuck in the pump you simply unbolt the valve covers, remove the check ball, find the blockage and you’re back in business. This is like a 5-10 minute process.

The Mud Sucker® B Series can pump up to 80 GPM and transfer fluids up to 300’ vertically so you will have plenty of pumping power. Keep in mind, that as wastewater gets thicker these values can vary. The pump you see above is shown with an off road utility trailer that we manufactured for the client’s needs. This is a heavy duty trailer but adapts to the tight New York City spaces that the pump must maneuver through. The best part is, we can manufacture these pumps and trailer systems specifically for your needs with hose bins, lockable storage containers and tanks for waste water collection and fresh water distribution.

Selecting Your Farm or Ranch Pump System

No one can argue that having a simple diaphragm pump for farm and ranch applications can be a lifesaver and time saver. Whether you’re pumping manure, silt from a pond, fruit juice or vegetable matter and more,having a trusted pump by your side can mean the difference between having aconsistently reliable pump and one that is nothing but hassles or in need of repair. Troy from Sandusky Ohio, has been a farmer in the area for decades. Here’s part of the discussion we had with him about his pumping needs and some recommendations we made:

“I’ve tried, Wacker, Varisco, Wilden and AMT pumps and none of them have been able to stand up to my needs around the farm. I’ve looked at your Mud Sucker and it seems like a heftier pump. I need to pump a bunch of different liquids including manure slurry, occasionally pulp slurry from our fruit farm and dewatering from our 2.5 acre pond. I’m looking for a diaphragm pump that will work in the 4” range that will attach to suction hoses. I currently have a 42 hp Kubota tractor PTO that could be a powering option (if you have anything for PTO mounting). What does Wastecorp suggest.”

Thanks –Troy, Sandusky OH

Troy, you are well on your way to getting what you need because you are following three simple principles: 1)know your application 2. Know your pump manufacturer and 3. Make your decision.

1. Know Your Application

We encourage all pump users to understand what they need their pump to do for them. This means knowing theaverage size of solids that go through the pump, what they will be using the diaphragm pump for and consider what the future future handling needs may be. This way, your sales rep will be better able to mage recommendations

2. Know Your Pump Manufacturer

Troy also knows his manufacturers. Some companies manufacture diaphragm pumps that are simply peripheral products for them, meaning they aren’t part of their core business or primary products. In short you are getting a pump from a big name that means nothing for yourapplication. At Wastecorp, our Mud Sucker Diaphragm Pumps are the core products of our company. We spend thousands of hours designing and perfecting mechanical diaphragm pump technology. They’re a bit more expensive to start but last the long haul and most customers admit they are worth every cent. Your spare parts needs are also lower with Mud Sucker’s than with other makes.

3. Make Your Decision

Once you have all the facts, consider what you need most. Do you want a trouble free pump that is designed for specifically what you are pumping or another make that was designed for a cookie cutter approach that may or may not work for the long haul.

Getting back to Troy’s issue, we finally recommended that Troy go with a Mud Sucker 4B-MDD trailer mounted. We designed a trailer specifically for his needs including a wide axle so he can tow the pump with his Kubota tractor. The double diaphragm configuration will allow troy to pump the thicker slurries like manure and the dewatering in his pond. We decided not to go with the PTO powering option even though this option is available for all Mud Sucker pumps. The Honda engine with auto start that we specified was selected for its durability and ease of use
