A gear pump is what you need. Like the SBC pump but a little bigger is better. I have a few different types of pumps that I use. I do have an extra gear pump for sale on a base that you could add your own 110V motor, I would like $40 plus shipping for it since that's what I paid. PM me if interested.
1. Teel pump with non self priming pump with 1" inlet and 1" outlet
Pros- I have it attached to a 2" banjo clamp so I can screw the 2" banjo fitting onto the bottom of my 250 gallon tote and it will empty a full tote in 10 min in 50 degree weather.
Cons- It is not self priming so you must suck from the bottom, which means there can not be chunks on the bottom, it will suck the thicker creamier stuff but does not like chunks of burger or fries. You also need a really good 110V plug in source for this 1hp motor.
2. Gear Pump with 4" pully mounted on a 2x8 with a 3/4hp electric farm duty motor and another 4" pully.
Pros- This is my main pump for collecting, you can suck off the top, I use 1" hose and a peace of 1" PVC as a wand and it works great, sucks about 15GPM but will pick up the this colder stuff with ease, the key for this pump is in the motor, I burnt through 2 fan blower motors and then switched to the 3/4hp Farm Duty motor and it works like a charm.
Cons- It takes 110V to power the motor, this is the only downside to this pump. I used some 1" Banjo fitting so I could keep the hoses stored separate and make it less messy for transporting.
3. Self Priming Trash Pump, if you are going to go with a trash pump get a self priming one IMO. I have a 3.5hp with a Teel pump and it works great. Has 2" hose and I use the same corigated hose for suction and discharge vs. the floppy blue hose for discharge.
Pros- No electricity required
Works very fast with the 2" hose and easy to make a pick up want by adding a 2" 90 degree street elbow a peace of 2" PVC pipe.
Cons- loud, not as quiet as those 110V pumps, but the convenience is worth it. Somewhat awkward and heavy but I leave it on my trailer vs. trying to load it into the truck every time.
