Pumps for cooking oil and waste trap grease

In this post we provide answers to the question of how to pump out used cooking oil from restaurant waste collection bins especially in colder weather? Used cooking oil transforms into a gel when the surrounding temperature dips below 40°F (4°C). This makes the fluid very difficult to pump. Roger F., from Charlotte, NC conveys the difficulty in pumping cooking oil:

“We are trying to find optimum pumping solution for pumping used cooking oil (uco) from 100- 300 gallon grease bins at restaurant accounts. We’ve recently opened a plant in the Charlotte area and have been pumping with a trash pump. It may have started off great but the trash pump failed after about six months as colder weather gelled the oil. We want a solution to Continue reading

Car Wash Waste Pit Pumps

Car wash waste pit pumps are an important waste management tool for the thousands of car wash locations in the United States, Canada and the world. Customers who are constructing new collection pits or retrofitting existing pits typically seek pump engineering support for the right equipment to do the job economically.

Planning Your Car Wash Pump Out System

The following question is one we hear often:
What kind of pump do you recommend for pumping out primary and secondary car wash traps with dual 500 gallon traps? How long does it take to pump out a 500 gallon pit?”
One of the most popular pumps for waste pit pumping is the Mud Sucker 2FA-M Series. With a 20 GPM transfer capability this pump is great for car wash waste. The waste pit generally becomes full with grit, silt, oil residue from cars and other oils. The pump must have the capability to transfer this variety of liquids. We also suggest placing the pump from 10-15 ft. from the pit with hosing to get the job done. Within 10 minutes for most applications the pit is empty.

Car Dealership Sump pit pump

If you can’t discharge into the municipal sewer system, we suggest a 500 gallon or above honey wagon. This can collect the car wash waste and then you can discharge at an approved dump station If you need a higher capacity pump we suggest going with the Mud Sucker 3FA Series with an 80 GPM capacity.

What Do Car Washes Typically Use To Pump Out Grit?

Wastecorp has worked with Ford dealerships, BMW dealerships and GM dealerships to standardize how their wash bay grit is pump out. It is typically a variation between a Mud Sucker 2B-M (shown in the photo above) and a Mud Sucker 3FA Series. All have worked well especially in the colder climate States and Provinces when you see lots of road grit in the winter washing down in the sump pits. Over 200 car dealerships, aircraft wash bays and maintenance terminals use Mud Sucker pumps in their sump pits to pump out grit. These pumps have worked well for airlines when cleaning and deicing aircraft and when transportation authorities clean off subway and bus grit. wi 

Silt Pumping Applications: What You Should Know

Silt Pumps - Mud Sucker

Silt Pumps – Mud Sucker

When we hear about silt pumping applications it usually involves pumping from a mining site, fruit juice concentrate or dredging application.  Often, job site operators have contained the silt-laden wastewater in either a holding tank or tote tank. Typically, the liquid waste must be treated or pumped to a larger containment area. As you can imagine, the internals of the pump must be able to handle the constant abrasive and gritty substances passing through it otherwise, the components will most certainly prematurely fail.

One of our mining customers in Nye County Nevada USA highlights a common application when pumping silt:

Our application involves pumping from two 1600 gallon cone tanks into a larger reservoir for treatment later on.  The liquid is a silt mixture from a mining operation.  We have tried some trash pumps and other submersibles but the grit keeps destroying the internals.   Do you have any product recommendations? Don M. Nye County, NV

In this case we recommended that Don use a professional double diaphragm pump with specialized valve chambers to better manage pumping silt. We also designed the pump with a double suction and double discharge arrangement so the operator could pump either one or two tanks at a time depending on which tank reached its capacity first.  The 2B-DD also includes butterfly valves to make pumping out one or two tanks a lot easier. When speaking with Don, we noticed that there might be the chance that the pump could become exposed to a closed valve in the system which may lead to pressure situation causing catastrophic damage to the pump. In this case, we engineered the Mud Sucker 2B-DD with pressure relief valves to help protect against any blockages in the line or a closed valve.

After six months, the pump is operating as expected with minor wear on the diaphragms and check balls. Given that the pump operates outdoors and on an eight hour /6 day a week schedule, the component wear is minimal. The Mud Sucker 2B-DD is an excellent custom solution for all kinds of silt application. More information is available here.

 

What You Didn’t Know About Double Disc Pumps

Wastecorp recently exhibited at a national water quality conference where we had a chance to discuss our exciting double disc pump technology with engineers, end users and pump distributors. We addressed some of the most common issues/questions below:

Can a Double Disc Pump Have Ball Valves?

Yes. In fact, ball valve technology is helping to usher in the next era of double disc style pumps. The ball valves help to break up solids and make pumping thicker municipal sewage easier. The ball valves also make it much easier to maintain the pump. With the traditional clack valve style double disc pump, debris can get stuck in the clack and trunnions which may reduce pumping productivity. With a Sludge Pro® Double Disc Pump you simply open up the valve chambers, check for any debris and blockages and get back to business.  Just because one type of double disc pump has a clack valve doesn’t mean others have to.

Is The Term Double Disc Pump a Registered Trademark?

No. In fact, it is unlawful for any one manufacturer to place a registered trademark “®” designation next to the generic term “double disc pump”. It hurts competition and misleads consumers.

Do You Have to Crawl Under a Sludge Pro® Double Disc Pump to Conduct Maintenance Like You Do Other Makes?

Absolutely not. Wastecorp would never design a pump where an operator or maintenance person had to crawl underneath a pump with hundreds of lbs potentially hanging overhead. This poses a safety risk and may lead to serious injury or death.

Is there really a difference between the clack valve style double disc pump and Wastecorp’s Sludge Pro Double Disc Pumps?

Yes. First, the Sludge Pro® includes a hydraulic jacking system that raises the shaft so the trunnion and wet section can be worked on while the maintenance person is standing up. Who would want to crawl underneath a pump to conduct maintenance?  Second, municipal sewage involves a lot of grit and solids to be pumped. Wastecorp designed a disc pump better able to manage solids and thicker sewage.  Third, you won’t find swan necks or clack valves on a Sludge Pro® A pump that involves removing the swan neck to access the pump internals may cause reduced productivity at a WWTP.  Belt and pulleys are another time waster that you won’t find on a Sludge Pro® double disc pump. Energy efficient direct drive systems reduce the motor hp required so the sewage pumping operation can operate more efficiently.

What is the difference between a single housing design and a three housing design?

A three housing design doesn’t really mean anything. It is the preference of the pump manufacturer. However a three piece pump body design may lead to increased parts to replace and repair and possibly more down time for the facility. A single housing design may improve access to the pumps internals and reduce the amount of pump maintenance people needed to work on the pump.

What drive systems are available for double disc pumps?

Electric driven and engine driven (usually) diesel are preferred by most facilities.

Where can I find Engineering Specifications on Double Disc Pumps?

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
