HYDRAcone – self priming head features a conical elastomer diaphragm. It is
particularly well suited for high-lift conditions, high viscosities, and low-density
slurries. It has a straight, flow through design and option slurry valves. The
HYDAcone is available in high performance fluorocarbon elastomers.

Double Diaphragm (Flat) with PULSAlarm Leak Detection – offers a rugged
sandwich style double diaphragm construction for increased protection against
leaks. PULSAlarm provides a pressurized leak detection technology to monitor
the diaphragm integrity and can signal an alarm or stop the pump at the first sign
of diaphragm failure. PULSAlarm is designed to contain full rated pressure up to
3,000 PSI (207 BAR), and is rated NEMA Type 7, EEMAC7 Class 1, Division 1,
Groups C&D, Class 1, Zone 1, Groups IIA&IIB; UL, cUL, CE, ATEX. An optional
pressure gauge is also available for visual indication of diaphragm integrity at the
pump.
Figure 8
Pump Head Assembly – attached to the intermediate head of the pump, it consists of the pump head,
cylinder, piston assembly, and three hydraulic valves.
Push-To-Purge (PTP) – situated at the top of the pump head
automatically removes gases from the hydraulic system during
normal operation. Momentary manual actuation of the external
valve button overrides automatic operation to validate priming
or to determine diaphragm integrity.
Figure 9
Hydraulic Performance Valve (HPV) – integrated within the
dish plate this valve automatically maintains the required
hydraulic oil volume by replacing any oil lost past the piston or
through the PTP valve.
