Tool Kits for Wanner Hydra-Cell Pro^® Pumps

On Wanner Hydra-Cell Pro^® pumps through D66 you can do standard maintenance with ordinary hand tools. Wanner^® still makes specialty tools that make the job cleaner, sold by model or as a full kit. Their datasheet is A03-991-2402. This article walks through what each piece does so you can buy the few tools you will actually use.

The complete kit for D/F/G/M series pumps is shown above. Each item:

1. Toolbox — ships with a complete kit. That kit holds every tool used on D/F/G/M sizes.
2. Inserter / rotator
   
   As an inserter it seats the shaft seals. Those seals are not a wear item, but if you split the housing for hydraulic-end work, replace them. Before we had the kit we used random sockets. The inserter is tapered to the right diameter so you do not roll a new seal. Use it with the seal protector (#5).
   
   As a rotator it lets you turn the shaft by hand. You can also jog the motor. On Kel-Cell and Pro fluid-end work you do not need to turn the shaft at all. You do need to turn it by hand when you put the cylinder housing back on the pump housing after hydraulic-end service.
   
   #7 is the rotator for hollow-shaft pumps.
3. Lever
   
   Used with seat puller #4. Each pump has 2 to 10 check valves in the head. They wear. Reclaimed-water duty often goes 9,000 hours; abrasive liquid is shorter. See check valve wear insights.
   
   The lever lifts the puller straight out of the valve plate. The seat O-ring is a tight fit in the plate bore. Inlet seats sit at the outer edge and pop out easily. Outlet seats are recessed and fight you. Without the lever and puller you pull the plate, flip it, and tap around the seat with a screwdriver. With the lever you leave the plate on the pump.
4. Puller — OD matches the model. Goes through the ID of the seat so you can pull by hand or with the lever.
5. Seal protector — the inserter pushes the seal in; this sleeve keeps the shaft from cutting the seal ID as the shaft goes back through.
6. Valve plunger holder
   
   The diaphragm is screwed to the plunger and valve plunger with a Phillips screw. The shaft is short and hard to hold with pliers. Each shaft has a cross-hole. Before this tool we stuck a small Allen wrench through that hole. The holder is sized to the hole and does not bend like a wrench.
7. Shaft rotator — for hollow-shaft pumps. Same job as the rotator side of #2.
8. and 9. Plunger guide / lifter — the plunger is the disc that joins the diaphragm to the valve plunger. Replacing it is uncommon. The tool threads match the diaphragm screw. Use it to pull the valve plunger out far enough for holder #6, or to separate the valve plunger from the plunger when you change the Hydra-Cell piston stack.
9. Assembly studs — draw the cylinder housing (spring-loaded pistons) back onto the pump housing after hydraulic-end work. Threaded studs and nuts so you can pull the two halves together slowly.

The tools most shops actually use are the lever, puller and valve plunger holder — those are the fluid-end tools. Check valves are the wear part. Diaphragms fail from temperature, over-pressure or chemistry. A lot of sites change diaphragms with the valves because the head is already open and the extra time and kit cost are small.

Vacuum Priming Kit

This is not in the boxed tool kit. It is worth having on its own.

A hand vacuum pump with fittings for the Hydra-Cell oil-fill cap. After a fluid-end job, pull 25 in. Hg and leave it 15 minutes. That pulls air from behind the diaphragms. It is faster and more repeatable than pressing on a diaphragm while you turn the shaft, “burping” air on pre-Kel-Cell designs, or depending on inlet pressure to purge the pistons.
