Holland Pump is committed to providing top-quality wellpoint equipment and systems designed to temporarily lower the groundwater table in a localized area, creating stable conditions for excavation and construction.
Our engineered solutions include pumps, riser pipes, header pipes, and all necessary components for efficient groundwater control.
Self-Jetting Wellpoint w/ PVC Screen Part
Fabricated around a 1.5” galvanized inner pipe, the wellpoint features a PVC plastic 0.015” slotted filter screen, a jet head with a plastic ball valve for jetting and a saw-toothed tip to penetrate hardpan layers or other tough ground strata. The top coupling threads to standard 1.5” riser pipe.
Self-Jetting Wellpoint w/ SS Screen
All the great features of our well known PVC screen steel self-jetting wellpoint, but upgraded with a 0.015” Stainless Steel mesh filter screen. The top coupling threads to standard 1.5” riser pipe.
PVC Wellpoint
–1-1/2” sch. 40 x 36” long
These economical wellpoints are used when a jet rod or punch and casing are used. An inside slip coupling is used so the wellpoint riser can be pulled and re-used.
Swing Joint - 1-1/2"
Tapered ends fit into the rubber grommets, expanding the grommets for an airtight fit in the header and wellpoint. No wrenches or tools are needed. Shut-off valve included to control water and air movement in the wellpoint.
Header Pipe - Grommet
6″, 8″, & 10″ Diameter Sizes
Made of rugged PVC plastic – one man can handle and carry a 20’ (6m) length. You save time and manpower on transportation, installation and removal. Header pipe is available in 6” (150mm), 8” (200mm), and 10” (250mm) sizes. Standard header pipe has 7 outlets per 20’ section. Close header for those extremely saturated jobs is available with 14 outlet per 20’ section. A selection of elbows, tees, angle fittings and end caps are available for all header sizes.
Dresser Couplings
6″, 8″, & 10″ Diameter Sizes
Used to connect PVC or hard pipe on pressure (discharge) side of pump.
Header Coupling
6”, 8″, 10″ Diameter PVC Pipe
Leakproof header connections are assured with the rubber slip fit sleeve coupling. Molded sleeves with a tapered ID fit quickly onto the header pipe.
VC Header Fittings
Schedule 40 – 6″, 8″, 10″ Diameter
Lightweight fittings are an alternative to steel on many sites. The sleevable design is the same OD as PVC pipe for quick and convenient hookup of the header pipe using our rubber header coupling. Available in 6″, 8″, 10″ schedule 40 – tee, 90°, 45°, 22.5° or end cap.
Grommet Inserts
Welltop grommet (left) and header grommet (right)
Grommet inserts are used to secure and seal swing joints to the welltop and header piping. Welltop insert is straight-walled to fit inside a 1-1/2” sch. 40 PVC coupling. Header inserts have a curved groove to fit inside a 2” hole in the PVC header. Fits 6” and 8” header systems.
Grommet Plugs
A simple, effective way to plug unused header pipe openings. Requires no tools.
QD Disconnect Clamps
6″, 8″, & 10″ Diameter Sizes
Header coupling connections are secured quickly and easily with Quick Disconnect “QD” style clamps. Simply pull the band around the coupling and push the worm screw in place. Minimal twisting of the screw with standard 5/16” nut driver is needed to finish tightening the unit. To loosen the connection, just remove tension and pop the screw from the band threads.
Pipe Puller Part
This fitting, attached to a crane or other lifting mechanism, makes removal of the installed wellpoint a quick, safe, and simple job. The bracket slips under the welltop, secured by the locking gate, and the wellpoint/riser pipe is then lifted straight out of the ground. The puller releases with a one-hand operation and is ready for use on the next wellpoint.
Jet Fitting
–1.5” Grommet Style Connection Size
Connected to the high pressure jetting hose, the jet fitting makes set-up for ‘jetting in’ the wellpoints a simple operation. The O-ring equipped jet fitting pushes into the Complete Welltop Adapter/riser assembly and a spring-secured bracket slips under the welltop to provide a leak-free pressure connection. Once the wellpoint is jetted in, the bracket is swung clear and the jet fitting pulled from the welltop, for use on the next wellpoint. No tools are required.
Wellpoint Mop
Mops are used for removing stubborn surface water from a dewatering site. The 20 ft. hose connects directly to the header system and transmits the pump vacuum to the mop head. The mop head can be moved to the lowest point to remove surface water down to within one inch of the mop base. Includes a ball valve to fine tune system depending on the water level. Heavy-duty steel to withstand most construction site abuse.
Wellpoint Strainer
Strainers can be used at the lowest point in an excavation to create a sump pit and remove unwanted water. Dig a hole approx. the size of a 5-gal bucket, place the strainer in a rock bed below the surface, hook the 20 ft. hose to the header pipe, and adjust the ball valve as needed. Strainers are made of durable steel to withstand most construction site abuse.
Aluminum Welltop
Grommet Style or O-ring Style
Used with the steel self-jetting wellpoints, the aluminum welltop threads onto your 1 ½” steel riser pipe and serves as the welltop connection point for your swing joint assembly. Part 302 has a 2” nominal opening that fits swing joints with o-ring style elbows. Part 302-GR has a 1 ½” nominal opening that accepts a rubber header grommet (sold separately) for swing joints used in a rubber grommet-type wellpoint system. The wide hex at the bottom of the welltop allows for the use of our wellpoint removal tool or nylon choker to grip the wellpoint more securely when removing the wellpoint from the ground.
Wellpoint Clay
Seals small leaks in the wellpoint system, header pipe, swings, pumps, etc. Doesn’t dry up like plumbers' putty, not messy like pipe compound
Jet Rod
Jet Rods makes jetting in a point simple. The rod and fittings are aluminum to cut down on weight and make handling easier. Jet Rod is 2-pieces to allow breakdown for easy transport and storage. Steel turbo tip blasts material out of the way for fast jetting and less wear.
Header Support
Designed simply to make the header line self-supporting by utilizing the strength of the riser pipes, a safety precaution in sheer cut area and valleys.
