having trouble.
May 29, 2019
I'm having trouble pumping my Umarex Gauntle, I am using the Foster quick-disconnect female to 1/8" BSPP male adapter but it won't pump more than 1000 PSI I needed to pump up to 3000 psi. what else can I usešŸ˜ž...??? & yes I used a Rubber seal. It goes up to 1000 PSI and it doesn't pump more than that and it starts leaking.

ProsIt is a very good quality hand pump

Good hand pump

The pump appeared to have been previously removed from its packaging and probably used, but I needed a fill source. The pump seems to work fine taking around 75 strokes to take my Bullboss from150 bar to 195 bar. Taking my time with a slight pause on the up and down strokes. Wouldnā€™t recommend trying to fill big tanks with it but works great on smaller ones!
ProsHigh fill pressure, it works
ConsLittle pricey, probably previously used
Best UsesSmaller tanks

Best hand pump out there

I have 3 hand pumps, an old Benjamin, a $40 Chinese knock off, and the Hill Mk4. The Hill Mk4 is by far the best hand pump I've ever used. Pumping my Discovery PCP to 2,000 psi is almost too easy and pumping my Vista Liberty to 3,600 psi is more work, but not bad. I wouldn't want to have to hand pump much higher than that very often, but have taken it to 4,000 psi and that's about as far as I was able to go. The Hill Mk4 is also more efficient at pumping. It takes fewer strokes and less heat is generated to achieve the same pressure as my other pumps.
ProsWell built More efficient / less work to use
Best UsesPCP air guns to 3,600 psi

Great pump.
December 27, 2018
This pump is great. I bought it with my first pcp rifle, and it's worked very well for me. I've been using it over a year, about 3 to 5 top offs a month. Hasn't seemed to wear at all, yet. I wasn't sure how long the seals would last before needing to be rebuilt. I also pump slow, but I pump right through without stopping. I have yet to notice it getting that warm that I would worry about the orings. Definitely recommend this pump, as an air source, or back up to your electric pump.
ProsWorks well.
ConsElbow grease.

This is a very well constructed pump. I have emptied 2tins of ammo through my gun so far and have used this pump to bring the pressure back to the top off. a good steady rythme with a momentery pause at the top and bottom of the stroke fills the 13 ci tank on my gauntlet in about 5 to 8min from 1800psi to 3000psi.
ProsEasily repairable/ rebuildable. Parts are much cheaper than purchasing a new c.f. fill station everytime they expire.
ConsThis is only a con because the optional moisture filter should not be an option. Adjust the price accordingly and only offer this pump with the moisture filter. At minimum the filter adds a layer of protection from air bourne debris the could potentially get in the pump , reducing the service life of the seals or the entire pump.

Quality Pump

This pump is made very well and the action is smooth. I'm not too fond of the air intake being so low to the floor where it can pick up debris.

When the lower part of the pump heats up make sure to take a break and let it cool down. Time will tell how long it will go between seal service.

ProsHigh quality
ConsAir intake is at the base of pump Plastic base

This is my first hand pump so I cannot compare to others. I based this purchase off reviews that stated fewer and easier pumps vs others. To fill 255cc reservoir from 100 bar to 200 bar, it takes 135 pumps. The pump does get hot so I break halfway to allow cooling. At pressures approaching 200 bar, resistance to pump does increase but is not too strenuous.

ConsGrips are too hard-should have some softer grips. feet should collapse for easier storage and transport.
