Bearing-Free Sealless Vertical Pumps

FOR CORROSIVE LIQUID PUMPING

ZDX AND ZKX PUMPS

Designed with no seals, no bearings and no wearing parts. They can even run dry.

These ZDX/ZKX series pumps are specially designed for in-tank or out-of-tank use. They’re built for heavy duty pumping of acid and alkaline solutions (pH 0-14), including electrolless nickel and copper and other corrosive liquids- at temperatures as high as 210ºF (99ºC). Fully portable, these compact Pumps can easily be transferred to different working areas as needed.

Patented, twin impeller design for high volume circulation and leak-proof operation.

The ZDX/ZKX series pumps incorporate a unique opposing twin-impeller design. This special Patented feature provides high volume circulation and eliminates leakage up the pump column, while minimizing entrained air. No bearings or seals and no wearing parts in the pump permit dry running without damage. Rugged, corrosion resistant CPVC (to 200ºF / 93ºC) or natural PVDF (to 210ºF / 99ºC) construction eliminates any metal contact preventing contamination or any reaction with corrosive liquids.

Pump Transfer Stations
"ZDX/ZKX" pumps can be provided as part of a complete pump station. Systems include an appropriately sized pump, liquid level control, corrosion resistant tank, tank cover, and necessary fittings and hardware.  pump stations are available in many standard, as well as custom sizes.

ACCESSORIES
"ZDX/ZKX" pumps can be equipped with a Bottom Strainer Assembly that can be used to draw liquid from deep in the tank and recirculate it, or pump to another location.

For initial priming, the liquid must cover the lower impeller. If the pump should lose its prime because it has been stopped or the liquid level dropped below the pump inlet, the liquid level must again rise to cover the impeller before pumping can resume.

Liquid Level Control
Automatic liquid level controls are available for any ZDX pump. These controllers feature two magnetic reed switches and are pre-wired to turn the pump on at high level. Additional switches may be added to control additional functions, such as turning on a second pump and/or an alarm.

All "ZDX/ZKX" series pumps are designed and built for rugged industrial service. They are fully field repairable should a part become damaged.

EASILY MOUNTS TO TANK
By means of a convenient mounting panel, the pump can be set in a self-priming position, in-tank, or outside the tank, as necessary.

MOTORS
"ZDX/ZKX" electric motors are all totally enclosed, fan cooled, UL recognized CSA approved and continuous duty rated. The motors are protected by a special corrosion resistant paint. In addition, they have a corrosion resistant drip cover.

The motors are equipped with over-sized, double sealed ball-bearings, and have a solid one-piece shaft to prevent impeller whip and assure long life.

All 1/6 horsepower and larger motors are equipped with a lip seal where the stainless steel shaft enters the motor. This helps vapors and liquid from entering the motor.
