SCHURCO Slurry
H Series: High Head, Heaviest Duty Slurry Pumps
|
H Series Profile:
• Discharge Diameters 1” to 4” (25mm to 100mm)
• Heads through 325ft (100m)
• Flow Rates through 3,000gpm (700m3/h)
• Casing Pressure Tolerance 750psig (5,170kPa)
Dimensionally interchangeable with Warman ® HH ® Series pumps.
Schurco Slurry® H Series pumps are fit for a variety of applications ranging from filter press feeds to pipeline transport staging pumps. The high heads along with sturdier wear parts makes these pumps some of the most rugged in the Schurco Slurry ® line. Extensive exterior ribbing allows for higher heads to be reached with a single pump, and bulked up wet end parts handle the toughest applications in the field today.
Typical H Series Applications
H Series Features
• WETTED PARTS
○ IMPELLERS – wide variety of metallurgic options – pump out vanes on rear and front (on closed impellers) reduce recirculation within pump, and aid in preventing seal contamination – optional castings of straight or semi-Francis vanes (from 3 to 8 vanes on certain sizes) offer wider hydraulic options in single sizes
○ LINERS – heavy-duty high chrome liner – active engineered attachment mechanism to casing via threaded bolts as opposed to unreliable glue
○ THROATBUSH – adjustable via cotters to account for wear over time and increase efficiency
○ CHEMICAL COMPATIBILITY – operating pH range from 3 to 14 – especially corrosive chemicals handled using diverse variety of elastomeric wetted parts
• SEALS– Schurco offers a wide variety of seal options to suit any process requirements
○ EXPELLER (CENTRIFUGAL SEAL) – available with low flow water flush or zero flow (grease lubricated) options to provide exceptional sealing where water introduction to the seal is intolerable or limited
○ STUFFING BOX – gland sealing with packing and lantern ring
○ SCHURCO LOW-FLOW SEAL – Schurco® offers a variety of low-flow seals, which can significantly reduce water usage in the stuffing box – the low-flow seal systems can be applied in a variety of applications using several material and component options
• BEARING ASSEMBLY – all bearings assembled with highest quality tapered roller bearings in controlled environments to prevent lubricant and housing contamination – oversized shaft diameters and reduced overhang in the wet end contribute to long life and reliability in the field
• CASING – split-case design allows for ease of access and maintenance on wet end parts – cast ductile iron with extensive exterior ribbing provides increased pressure ratings and reliable service over time – series pumping easily achieved with casing pressures rated to 750psig
• BASE – a single piece base with integrated adjustment mechanism for impeller clearance within pump – bearing assembly locks into base using four heavy-duty bolts – three custom designed mounting modes available: overhead using integrated single pedestal system, side-by-side with adjustable motor mount, and direct-coupled with precision in-house alignment (optional VFD packages available)
