Page 10 - Benjamin Hand Pump, Fits Crosman Reviews

Lowest price. Easy to take apart and maintain o-rings/lube.

Need a moisture trap to filter the air AFTER it has been pressurized.

My pump failed after a year. Had it repaired by Sun Optics. Apparently, the o-ring (part #30) was frayed and torn. Via Marauder forum, I learned how to take it apart, lube it, clean it and replace o-rings (must use hard 90 Durometer Viton rings). I even added a inline moisture filter (filled with blue dessicant balls). Not much help. This time the o-rings held up fine. But, moisture kept collecting at the base - resulting in Vapor lock? Won't be getting this pump again. Instead, looking at shoebox compressor in the future. Will likely buy the Hill pump too.

High quality and well made, seems really tough, not garbage like a tire pump.

These pumps should come with an air dryer, or have an air dryer option.

This is a lot of work but it is very compact compared to the scuba tank. I think that the way it works out for me is about 3 pumps per shot for my .25 cal Marauder to get from 2,000 psi to the max of 3,000 psi. It's really handy when your scuba tank starts losing pressure and you just want to finish filling the res. up to max for a quick trip into the woods.

Very nice quality product.

Some type of a clip that would hold the air line for better storage.

For filling a gun with 0 psi it take a little more then 40 pumps, but filling when above 2200 psi it's less then 10 pumps. I can fire 20 pellets and only lose 200-250 psi.

its reliable

weight and foot bracket thickness

its heavy theres no moisture filter on the intake the hose is shorter than id like other than that ive had no issues with mine its been very dependable

nothing

the screws that attach the footplate to the pump are very low quality and soft

this pump breaks very easily and if you send it back to the company (sunoptics usa ) they will not fix it. ive had to send it back two times now and both times it has worked for about a week and will break again, in my case the upstroke is nearly impossible and the downstroke was impossible even with all 185 pounds of me on the pump it would not go down, dont buy this pump

I've had this pump for about 9 months now without any problem, up to 3600psi, sturdy, very good gauge it is equal to the Mord's gauge all times, color & design.

longer house & offer other adapters for other PCPs.

Just let the pump getting cold during pumping, you will have this pump for a years, warming up is only a weak point for this pump, use silicone grease for protecting the main tube & being easy to pump, I got this as a part of a big deal of my Mrod, Pyramid Air is a good company to deal with.

Feals like a quality made product but does not last.

Reliability.

I have had this pump for less than a month and it has stopped working twice. I had to take it apart and rebuild it. This pump is known for its poor quality.

I got this as part of the package deal with my Marauder .177. It worked for about a month and them wouldn't draw air in like others have commented about.

I would upgrade to the Hill pump instead of getting this one again. It is worth the extra money to get a higher quality more reliable pump to start with. The Hill pump is also much easier to rebuild and all of the parts are avaible from Pyramid Air.

After doing some research on line this is a common issue with this pump. I did a rebuild myself to save time, the 3rd stage o-ring is the common failure point, I picked up the rebuild kit on line and used a high quality molly grease on the o-rings, also removed the water build I found inside the pump tubes. To prevent this in the future I added a water absorption filter between the pump base and brass screen air filter. Now it works like a champ and pumps much easier. Apparently the cheap lube used by the factory along with moisture entering the pump deteriorates the o-rings very quickly. If these simple steps wouuld have been done by Crosman it would make this a nice pump for the price. At the time I had no backup so i couldn't use my PCP rifles until I fixed it myself. Since them I have picked up a Hill pump and keep this as backup.

Robust construction.

50 pumps needs cool down/bleed water.

lightweight sturdy great for the price i lost 10 pounds doing this lol

longer hose

at first it was impossible for me to pump pass 2400psi it was literally lifting me off the ground but after a week that stopped and pumping became a breeze i like pumping rather then spending alot of money on a scuba tank, this is a great workout

its easy to use and familiarize, the material used is relative to its pricing. it does the job of filling my marauder easily, no frustrations and very accurate on its functions.

the foot plate should have a rubber padding under to achieve a firm based footing and protects the finish from some rough floor surfaces.

this is recommended for Benjamin Marauder Pistols for it fills the reservoir tube easily with minimum effort in a short time. its good to have one.

Overall quality is very nice. It appears to be well designed and made.

Air output was very low. Takes a long time to fill the res. on the Marauder.60 to 70 pumps with increasing difficulty... quite a workout.

Get a scuba tank instead and you'll have more fun shooting. Instead of waiting from your heart rate to go down you can plug it in and in 3 to 4 seconds have a full tank and be up and shooting.

Very well made, feels solid and is easy to use.

Maybe just a bit expensive.

cheap way to fill your gun

longer hose

takes some time to fill your gun when it is empty,also takes quite a bit of effort to pump

Full size handle

Reliable would be a start

I purchased the package deal with my .25 Marauder. I was only able to fill my Mrod 6 times on the 7th time a seal rolled over inside or something because it couldn't draw air in and would suck the pump handle back down. I ordered an Axcel since the high rated Hill pumps were back ordered a couple weeks. The Axcel is faster and much easier to use then the Benjamin. Also has done about 20 something fillings without a hitch. In a nutshell save your money and do not get the package deal.

Easy to use and a cheap way to fill my Marauder.

Longer hose. The hose is too short to fill the rifle unless it is lying on the ground.

Pump slow and steady. Seems to work best when you take your time and make sure to pause slightly on the top and bottom of the stroke.

Easy to set up and simple to use.

Make a better set of instructions! I had to ask others how to properly use this! Not good to have to do that!

This is cheap, easy to use, and reliable.

Although there are problems reported out there I have had none. It does give you a bit of a workout if you let pressure get very low. Everyone needs a bit of exercise right...

Maybe a longer air line

Not sure I am going to like the pump. I tried to use it on my Marauder that was at 2000lb. I wanted to increase the pressure to 3000lb. I did not have the weight or strength to do so. I weigh 190lb and just could not push on the pump enough to increase the pressure in the gun.

The air hose is much to short
